tools: unify channel and memory tools, clean up mcp-server

Move all tool definitions and dispatch out of mcp-server.rs:
- Channel tools: new tools/channels.rs with definitions, async
  dispatch, blocking dispatch, and capnp RPC helpers
- Memory tools: make tools/memory.rs pub so mcp-server can use it

mcp-server.rs is now pure JSON-RPC protocol plumbing (482 → 169 lines).
No tool-specific code remains in that file.

Also removes duplicated channel RPC helpers and fetch_all_channels
that were in both mcp-server.rs and thalamus/channels.rs.
