v0.4.0

Added

• unwritten ignore <trigger> <hole> --for <n> — bounded mute for a
  persistently false rule. Expires after the trigger has changed n more
  times (default 30; those are the commits that erode or re-confirm the rule),
  shows as suppressed with the remaining budget rather than disappearing,
  is overridden by check --strict, and lives in machine-managed
  .unwritten/ignores.json. --list / --remove manage entries; expired
  entries are pruned automatically. Deliberately CLI-only — no MCP tool, so
  agents cannot mute their own warnings. Permanent ignores do not exist by
  design: unbounded mutes go stale and eventually hide real omissions.

Changed

• Refreshed project artwork (package icon, registry icons, social card).
