A transient DB lock in breaker.record_failure() inside an except handler
killed the asyncio coroutine permanently — snapshot_cycle died Apr 18 and
never recovered. All three breaker call sites now have their own try/except.
Also includes HTML injection fix for github_feedback review_text.

github_feedback.py posts pipeline status to GitHub PRs at three touchpoints:
discovery ack, eval review result, and merge/close outcome. Only fires for
PRs with a github_pr link (set by sync-mirror.sh). All calls non-fatal.
contributor.py: expanded git author fallback to scan all non-merge commits
(was only checking last commit), added teleo-bot and github-actions[bot]
to bot filter list.
