v0.4.0

Fixed

• _extract_area() marker semantics documented and pinned by tests:
  the CI gate matches the hooks (first matching line, last
  AREA:/LOG: marker on it).
• status_token() strips the en-dash as well as the em-dash (OPEN– ->
  OPEN).
• cmd_revise() / cmd_resolve() use the already-read text instead of
  re-reading the log (one read, no stale-write window).
• load() reads with utf-8-sig so a BOM-prefixed log is parsed.

Added

• --review proposals now quote each reversal's REASON, so the draft
  shows why the decision kept changing.
• Robustness tests: 100-decision fuzz, BOM / invalid UTF-8, en-dash
  statuses, multi-marker precedence in --check-commit, and the manual
  LOCKED + SUPERSEDES path through --decide.
• --stats analytics command: status mix, current/superseded counts,
  reversal rate, average time from LOCKED to REVISED, and the most
  volatile topics.

Docs

• Document the _topic_of grouping heuristic (--review / --stats):
  first FILES basename, else first 3 title words; same basename in
  different dirs merges.
