- README: update lede, architecture block, self-improvement section, status.
Mentions knowledge.db, coach/advice loop, persona narration, and the new
PR-based auto-patch flow.
- scripts/auto-patch.js: replace cherry-pick-to-main with `git push` +
`gh pr create`. The operator is now the only one who can merge into main
(enforced by branch protection rules on the remote). Legacy direct-merge
path remains behind PEPA_AUTO_PATCH_MERGE=cherry-pick for emergencies.
