load_all() now builds a _tools: dict[str, Tool] index at startup.
get_all_tools() returns list(_tools.values()) and find_tool() is a
direct dict.get() instead of rebuilding the full tool list from every
plugin on every tool call during a session.
Updated test helper to populate _tools alongside _plugins to match
the actual load_all() behaviour.
