weekly-review: Turning Weekly Reviews from a Journal into a Closed Loop

The `weekly-review` plugin solves the problem that weekly reviews often reduce to mere emotional logs. By enforcing strict reconciliation between commitments and outcomes, it converts reviews into an actionable closed loop. Maintained by ChenneyZhuang, its core features include retrieving commitments, reconciling statuses with attached evidence, deferring unfinished items, and setting concrete commitments. It requires users to log entries in `reviews.md` and monitors goal drift by comparing records across weeks. Although it runs with the current process privileges, it effectively improves workflow reliability and execution by establishing evidence-based baselines and honest records.
