feat(plugins): Stage 2.1 — plugin framework and AI tool-use

Introduces a standalone plugin system where every integration lives as
an independent Python script in ~/.pyra/plugins/, not hardcoded in core.

Plugin framework (src/pyra/plugins/):
- base.py: Tool dataclass, PyraPlugin Protocol, BasePlugin helper
- loader.py: importlib-based discovery; one bad plugin never crashes pyra
- registry.py: singleton aggregating tools, slash commands, system prompts
- executor.py: approval gate — scans args, prompts y/N, scans result, logs
- install.py: copies bundled_plugins/ to ~/.pyra/plugins/ on install

Chat integration:
- AI tool-use loop (litellm function calling, up to 10 iterations)
- Plugin system prompt additions injected per session
- Plugin slash commands merged with static commands

CLI additions:
- pyra plugin list/install/enable/disable/setup
- pyra daemon start/stop/status/restart/install/uninstall (stubs for 2.4)

Config: PluginConfig + DaemonConfig added to PyraConfig (backwards-compatible)
Bootstrap: ~/.pyra/plugins/ and ~/.pyra/logs/ created on startup
Security: tool args and results always injection-scanned; plugin dirs
validated with assert_safe_path() before loading (symlink protection)

Tests: 37 new tests (loader, registry, executor, plugin isolation security)
161 total, all passing.

 ## 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 2.1 — Plugin Framework: complete** (2026-05-17)
+Next: Stage 2.2 (Nextcloud plugin) + Stage 2.3 (Email plugin)
 
 ## 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
-Shell (.sh), PowerShell (.ps1), and Python (.py) scripts in `~/.pyra/skills/`. The AI
-can suggest running a skill, but execution requires explicit user approval (y/n prompt).
-No skill can access the vault. Skills are discovered by the pyra CLI, not by the AI.
+### Stage 2 — Plugin System & Integrations (IN PROGRESS)
+
+Pyra runs as a system daemon so messaging bots are always-on. All integrations are
+standalone Python plugin scripts in `~/.pyra/plugins/` — not hardcoded in `src/pyra/`.
+The AI uses tool-use (function calling) to invoke plugins; every execution requires
+explicit user approval (y/N prompt). Plugin credentials are stored in the vault under
+namespaced keys (`plugin:{name}:{key}`).
+
+#### Stage 2.1 — Plugin Framework ✅ COMPLETE
+- `src/pyra/plugins/` package: `base.py`, `loader.py`, `registry.py`, `executor.py`, `install.py`
+- `src/pyra/bundled_plugins/` — ships bundled plugin scripts with pyra
+- `src/pyra/daemon/` stub (CLI surface only)
+- 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
+
+#### Stage 2.2 — Nextcloud Plugin (next)
+Bundled plugin: `src/pyra/bundled_plugins/nextcloud/plugin.py`
+CalDAV calendar, CardDAV contacts, WebDAV files.
+Install deps: `uv pip install -e ".[nextcloud]"`
+
+#### Stage 2.3 — Email Plugin (next, parallel with 2.2)
+Bundled plugin: `src/pyra/bundled_plugins/email/plugin.py`
+IMAP (Hotmail.de/Outlook), folder browsing, smart event extraction to calendar.
+No new deps (uses stdlib imaplib).
+
+#### Stage 2.4 — Daemon + Messaging Bots
+- `src/pyra/daemon/server.py` — asyncio event loop, plugin tasks, IPC socket
+- `src/pyra/daemon/ipc.py` — Unix socket (chmod 600), line-delimited JSON protocol
+- `src/pyra/daemon/service.py` — launchd plist (macOS) / systemd unit (Linux)
+- Bundled plugins: `matrix_bot`, `telegram_bot`, `signal_bot`
+- Security: sender allowlist, bcrypt passphrase challenge, rate limiting (20 msg/hr),
+  injection scanning on all incoming messages, tool approval over messaging (2-min timeout)
+
+#### Stage 2.5 — Infrastructure Plugins
+Bundled plugins: `ssh_tool` (paramiko), `docker_tool` (docker SDK),
+`kubernetes_tool` (kubectl subprocess), `service_manager` (systemctl/launchctl),
+`smb_mount` (mount subprocess)
+
+#### Stage 2.6 — Cloud Storage Plugins
+Bundled plugins: `gdrive` (Google OAuth2), `onedrive` (MSAL device flow), `dropbox_tool`

+### 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, 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 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)
