chore(email): sharpen tool descriptions and rename email_list_inbox

- Rename email_list_inbox → email_list_folder (works on any folder, not just inbox)
- email_list_folder / email_search: distinguish browse-by-recency vs filter-by-query
- email_move / email_delete: clarify single-email scope; point to email_bulk_action for multiple
- email_bulk_action: clarify it handles multiple emails; point to move/delete for single
- email_create_folder: remove redundant "ask user" instruction (requires_approval handles it)
- Update tests to reflect renamed tool

 ## What Is This
 
 Pyra is a personal AI assistant CLI combining a multi-provider AI chat interface with
-an automation/skills system (Stage 2+) and an encrypted vault (Stage 3+).
+a plugin/integration system (Stage 2+) and an encrypted vault (Stage 3+).
+
+## Current Status
+
+**Stage 3 — Memory Database: complete** (2026-05-18)
+**Stage 6 — Daemon infrastructure: in progress** (`feat/daemon` branch)
+Next: Stage 4 — Vault Encryption (skipped for now); messaging bots (Stage 6 remainder)
 
 ## Project Roadmap
 
-### Stage 1 — Core CLI (current)
+### Stage 1 — Core CLI ✅ COMPLETE
 Working `pyra` executable with provider setup wizard, streaming chat REPL, .md-based
 memory in `~/.pyra/memory/`, and hard security boundaries around the vault.
 
-### Stage 2 — Skills / Automations
+### Stage 2 — Plugin Framework ✅ COMPLETE
-Shell (.sh), PowerShell (.ps1), and Python (.py) scripts in `~/.pyra/skills/`. The AI
+- `src/pyra/plugins/` package: `base.py`, `loader.py`, `registry.py`, `executor.py`, `install.py`
-can suggest running a skill, but execution requires explicit user approval (y/n prompt).
+- `src/pyra/bundled_plugins/` — ships bundled plugin scripts with pyra
-No skill can access the vault. Skills are discovered by the pyra CLI, not by the AI.
+- `src/pyra/daemon/` stub (CLI surface only; daemon itself is Stage 6)
+- Config: `PluginConfig` + `DaemonConfig` added to `PyraConfig`
+- Bootstrap: `~/.pyra/plugins/` and `~/.pyra/logs/` created on startup
+- Chat session: AI tool-use loop (up to 10 iterations), approval gate, plugin slash commands
+- CLI: `pyra plugin list/install/enable/disable/setup`, `pyra daemon *` (stubs at Stage 2; implemented in Stage 6)
 
-### Stage 3 — Vault Encryption
+### Stage 3 — Memory Database ✅ COMPLETE
+- `src/pyra/memory/database.py`: SQLite + FTS5 via `memory_meta` + `memory_fts` tables
+- `memory_meta` columns: `path`, `category`, `size_bytes`, `modified`, `summary`, `keywords`, `embedding BLOB` (reserved for Stage 8)
+- `list_memories()` queries DB; `lookup_memories()` uses FTS5 with JSON-index fallback
+- `write_memory()` / `append_memory()` upsert to DB on every write
+- `bootstrap()` calls `init_db()` + `migrate_from_files()` (one-shot migration of existing `.md` files)
+- `.md` files remain the canonical store; DB is the search index
+
+### Stage 4 — Vault Encryption
 Encrypt `~/.pyra/vault/secrets/` using `age` (or GPG fallback). Pyra decrypts in memory
 at call time only — no plaintext ever written to disk after initial setup. Secret
 rotation support. Per-key passphrases optional.
 
-### Stage 4 — Security Audit Sub-agent
+### Stage 5 — Skills System
-A separate `pyra security audit` command that spins up a sandboxed AI agent whose sole
+YAML-defined multi-plugin workflows with event triggers and AI-driven selection.
-job is scanning for vulnerabilities: prompt injection in memory files, unexpected vault
+Skills compose existing plugin tools into automated pipelines with conditional branching
-access attempts in `security.log`, outdated dependency CVEs, permission drift on `~/.pyra/`.
+and human-in-the-loop decision points.
+
+### Stage 6 — Daemon + Messaging Bots
+Always-on asyncio daemon, IPC socket, launchd/systemd service. Bundled bots:
+`matrix_bot`, `telegram_bot`, `signal_bot`. Sender allowlist, bcrypt passphrase
+challenge, rate limiting (20 msg/hr), injection scanning on all incoming messages,
+tool approval over messaging (2-min timeout).
+
+### Stage 7 — Security Audit Sub-agent
+`pyra security audit` — sandboxed agent scanning for prompt injection in memory files,
+unexpected vault access in `security.log`, outdated CVEs, permission drift on `~/.pyra/`.
 Report written to `~/.pyra/security_audit.md` (not AI-readable during normal chat).
 
-### Stage 5 — Web UI / Advanced Features
+### Stage 8 — Web UI / Advanced Features
 Optional local web interface (FastAPI + HTMX or similar). Embedding-based memory search
-(ChromaDB or sqlite-vec). Scheduled automations via cron-style skill scheduling.
+via `sqlite-vec`. Multi-profile support (work vs personal).
-Multi-profile support (work vs personal).
+
+---
+
+### Plugin Catalog (not stage-gated — ships when ready)
+
+Plugins are developed independently on `plugin/<name>` branches and merged to `main`
+only when complete. All integrations are standalone Python plugin scripts in
+`~/.pyra/plugins/` — not hardcoded in `src/pyra/`. Plugin credentials are stored in
+the vault under namespaced keys (`plugin:{name}:{key}`).

+### Plugin Credential Naming Convention
+
+Plugin credentials live in the vault under namespaced keys:
+```
+plugin:{plugin_name}:{key_name}
+```
+Examples: `plugin:nextcloud:password`, `plugin:matrix_bot:access_token`
+
+The vault's `get_key()` / `set_key()` accept any string — the namespace is enforced
+by convention in each plugin's `setup()` method.
+
+### Writing a Plugin
+
+1. Create `~/.pyra/plugins/<name>/manifest.json`:
+   ```json
+   {"name": "<name>", "version": "1.0.0", "description": "...", "author": "you"}
+   ```
+2. Create `~/.pyra/plugins/<name>/plugin.py` exporting `get_plugin() -> BasePlugin`:
+   ```python
+   from pyra.plugins.base import BasePlugin, ConfigField, Tool
+
+   class MyPlugin(BasePlugin):
+       name = "<name>"
+       description = "..."
+       version = "1.0.0"
+
+       def on_load(self, vault_reader):
+           self._secret = vault_reader("plugin:<name>:secret")
+
+       def tools(self):
+           return [
+               Tool("my_tool", "Does X", {"type": "object", "properties": {}},
+                    self._do_x, requires_approval=True)
+           ]
+
+       def _do_x(self):
+           return "result"
+
+       def setup(self, console, vault_writer):
+           secret = console.input("Enter secret: ")
+           vault_writer("plugin:<name>:secret", secret)
+
+       def config_fields(self):
+           # Declare user-adjustable settings. Values are saved to config.yaml
+           # under plugin_settings["<name>"] and rendered in /config → plugin tab.
+           return [
+               ConfigField("api_url", "API URL", "text", "https://example.com",
+                           description="Base URL for the service"),
+               ConfigField("verify_ssl", "Verify SSL", "bool", True),
+           ]
+
+   def get_plugin():
+       return MyPlugin()
+   ```
+3. `pyra plugin enable <name>`
+
+**Plugin rules:**
+- Never import from `pyra.vault` directly — use the `vault_reader`/`vault_writer` callables
+- All write/destructive tools must set `requires_approval=True`
+- Return strings from tool handlers (truncated to 4000 chars by executor)
+- Implement `config_fields()` for any user-adjustable settings beyond credentials.
+  Return a list of `ConfigField` objects — the `/config` TUI renders them automatically
+  and saves values to `config.yaml` under `plugin_settings["<name>"]`.
+  Plugins that need no configuration can omit this method (base no-op is used).

+
+## Workflow Rules
+
+### Testing
+
+- **Write tests for every new feature.** A feature without tests is incomplete — do not commit without them.
+- New tests go in `tests/unit/` for pure-logic helpers and `tests/security/` for security-boundary code.
+- All existing tests must continue to pass — run `pytest tests/ -v` before committing.
+- Test pure functions directly; do not test interactive I/O (questionary, Rich output) — only test the logic helpers those flows call.
+- For Rich output, capture side effects by monkeypatching `console.print` rather than using `capsys`.
+
+### Bugfixes
+
+- **Stay under 50 lines changed.** Find the root cause and fix it directly.
+- If the fix seems to require more than 50 lines, it is probably a refactor, not a bugfix — stop and discuss with the user before proceeding.
+- Do not write workarounds, fallback layers, or compatibility shims to route around a bug. Remove the cause.
+
+### Committing Changes
+
+- **Commit after every logical unit of work** — do not batch unrelated changes into one commit and do not wait until the end of a session.
+- **One commit per concern.** If a session touches a file for two different reasons (e.g. a bugfix and a cleanup), those are two separate commits — staged and committed independently, even if the file is the same.
+- Use the project commit convention: `feat(module):`, `fix(module):`, `test:`, `docs:`, `chore:` followed by a short description.
+- Always `git add` only the files relevant to that commit — never `git add .` blindly.
+- **Always push after committing** — every commit goes to the remote Gitea repository immediately.
+
+### Git Worktrees — Required for All Branch Work
+
+**Never switch branches in the main working directory.** Always use a git worktree so that
+multiple sessions (plugins, features, bugfixes) can run in parallel without interfering with
+each other or with `main`.
+
+```bash
+# Create a worktree for a plugin branch
+git worktree add ../pyra-plugin-nextcloud -b plugin/nextcloud
+
+# Create a worktree for a feature branch
+git worktree add ../pyra-feat-vault -b feat/vault-encryption
+
+# List active worktrees
+git worktree list
+
+# Remove a worktree after merging
+git worktree remove ../pyra-plugin-nextcloud
+```
+
+Each worktree is a full checkout at a separate path. Work on it exactly like the main repo —
+commit, push, run tests — without touching the `main` worktree.
+
+**Rules:**
+- The main working directory (`/Users/nik/Documents/Progamming/pyra`) always stays on `main`.
+- Do **not** run `git checkout <branch>` in the main directory — create a worktree instead.
+- When a Claude Code session is asked to work on a branch, it must create (or reuse) a worktree
+  for that branch before making any changes.
+
+### Plugin Branches
+
+- Every plugin is developed on its own branch: `plugin/<name>` (e.g. `plugin/nextcloud`), in its
+  own worktree (e.g. `../pyra-plugin-nextcloud`).
+- A plugin branch is **never merged to `main` until the plugin is complete and tested**.
+- `main` always contains only production-ready core source code (`src/pyra/` framework).
+- If plugin work uncovers a bug in core Pyra code, fix it on a dedicated `fix/...` branch
+  off `main` (in its own worktree), merge to `main`, push, then rebase the plugin branch.
+- Plugin branches may be pushed to remote for backup/review at any time.
+- Do **not** merge plugin branches to `main` prematurely — a half-working plugin on `main`
+  is worse than one that isn't there yet.
+
+### Avoid Duplication — Check the Inventory First
+
+Before writing any new utility function, class, or import block, check the **Code Inventory** section below. Everything listed there already exists and is importable. Writing a duplicate wastes code and introduces divergence.

+## Plugins
+
+Pyra has an extensible plugin system. Bundled plugins are shipped with Pyra and installed on
+demand; third-party plugins can be dropped into `~/.pyra/plugins/` directly.
+
+Each plugin is a directory containing a `manifest.json` and a `plugin.py`. Plugin credentials
+are stored in the vault under namespaced keys (`plugin:<name>:<key>`) — never in `config.yaml`.
+
+```bash
+pyra plugin list                  # see what's available
+pyra plugin install <name>        # copy a bundled plugin to ~/.pyra/plugins/
+pyra plugin setup <name>          # enter credentials (stored in vault)
+pyra plugin enable <name>         # activate for the next chat session
+```
+
+## Multi-step Planning
+
+When given a complex task the AI can propose a **multi-step plan** using the built-in
+`plan_and_execute` tool. Pyra prints the plan and asks for approval before executing
+anything. Each step runs as a separate AI call with access to enabled plugin tools; each
+result is verified before moving on to the next step. You can decline the plan or
+interrupt at any point.
+
