0.6.0

Added

• events list finds events from their earliest start: starts_at>=<date>. starts_at now takes either side
  and a range: starts_at>=2026-11-02, starts_at:[2026-11-02 TO 2026-11-07}, and starts_at:2026-11-02 for the
  events of one day. An event that starts exactly at the moment is kept; an all-day event is compared by its date in
  your time zone. In 0.5.0 starts_at>=… was refused. ends_at is unchanged: an earliest end only, strictly after.

Changed — may break callers

• session start falls back to a private file when the keyring fails, and never asks. It used to
  stop with oauth.not-saved and tell you to pass --credential-storage file. Now it signs in, says once on stderr
  that it used credentials.json in the state folder, and answers credential_storage: "file". The flag still
  chooses the file outright; the keyring is still the default and the safer choice. session status and
  session end no longer answer keyring: "unreachable": the keyring's failure is the stderr warning.
• A run with moved folders names its temporary keyring entry after its state folder, where it used to name it after
  its config folder; a temporary entry an older run left is no longer read. bin/keyring-dedupe removes it.
• calendars busy takes the standard field query, and none of its own words. today, week, from: and to:
  are refused. The window is the answer's own start and end: from:2026-11-02 to:2026-11-06 is
  start>=2026-11-02 end<=2026-11-06, and today is start>=today end<=today. Without start the window starts
  today, without end it lasts seven days, so a bare calendars busy is still this week. calendar: and person:
  stay and may still be repeated. Over MCP the input is query, no longer words. The first screen shows
  calendars busy --duration-minutes 30.
• gcal needs @wirecat/cli-base 0.67 and @wirecat/cli-core 0.502, which now build store status,
  search events <query> and the field queries themselves; the commands, their answers and permission keys are the
  same as in 0.5.0.
