- Add source health columns (last_success_at, last_error_at, last_error,
consecutive_failures, review_flag, review_reason) via SCHEMA + migration.
- poll_source maintains them: success resets the failure streak and records the
success time; failure increments it and stores the latest error.
- review_sources() flags active sources that are stale, repeatedly failing,
low-acceptance, duplicate-heavy, or doom-skewed (high cortisol/ragebait) over
a recent window. It is purely advisory: it sets review_flag/review_reason and
never changes the active column (human stays in the loop), clearing the flag
when a source recovers.
- CLI review-sources; cycle runs it as a final step (--no-review to skip);
source-report shows a review line for flagged feeds.
- Tests: healthy/failing/stale/low-acceptance/recovery and never-deactivates.
