Tool definition quality pass. Every MCP tool now serializes a human-readable
title, an annotations block (readOnlyHint, openWorldHint, plus
idempotentHint on reconcile), and — for the 17 tools whose response is
pure structured JSON — an outputSchema describing the response shape.

Added

• title, annotations, and outputSchema on all 19 MCP tools. Two
  helper constants (_READ_ONLY and _RECONCILE_HINTS) at the top of
  mcp_server.py keep the per-tool blocks readable.
• Anti-pattern callouts in the descriptions of the four lowest-scoring
  tools (get_stats, replay_file, get_project_timeline,
  get_session_commits) and the borderline tools (find_episodes,
  get_episode, find_commits, list_projects, list_sessions,
  get_file_history, replay_file) — every tool description now names
  what NOT to use it for, making tool selection sharper.
• server.json description tightened to mention tool count and capability
  grouping.

Why

GLAMA scores MCP tool definitions on six dimensions, with outputSchema
and annotations being two MCP-spec fields most directly tied to
"Behavioral Transparency" and "Contextual Completeness." This release adds
both across the surface so MCP clients (and ranking sites like GLAMA) can
treat each tool as documented metadata rather than free-form prose.

No behavior changes. No breaking schema changes.
