Librarian Tools Collapse (16 → 5)

The 16 individual librarian tools have been collapsed into 5 action-dispatched tools, reducing MCP surface area and improving discoverability.

New tools

Usage

Every tool takes a required action parameter:

// Find active trackers
{"action": "find", "kind": "tracker", "status": "active"}

// Get one artifact with links
{"action": "get", "id": "abc123", "include_links": true}

// Append a note event
{"action": "create", "artifact_id": "abc123", "kind": "note", "payload": {"text": "..."}}

// Gather refresh context
{"action": "gather", "id": "abc123"}

// Pack context bundle
{"action": "context", "topic": "authentication"}
