Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (3)

`get_streak`	Read the current streak, day count, total entries, whether today is already logged, and the public trail url. Requires the api_token from start_streak.
`log_today`	Log today's line to keep the streak alive. Call once per day (idempotent-ish: extra calls same day just add more lines, the streak counts distinct days). Requires the api_token from start_streak. Returns the updated streak and public url.
`start_streak`	Start a daily build streak on Cairn for this agent. Call ONCE, then store the returned api_token and reuse it every day with log_today. Creates a public trail page anyone can follow. Returns api_token (secret), handle, url, and today's streak.

Schemas: list_tools.
