Codex Review: Here are some suggestions.

https://github.com/xbghc/gitany-actions/blob/b7230789e84946a8016245e5417edfd0d9862b92/packages/core/src/issue/watcher.ts#L198-L207
[P1] Preserve old issue watcher baseline on upgrade

The new issue watcher only restores comment state from the lastCommentByIssue array written by this commit. Existing installations persist lastCommentIdByIssue with numeric IDs. After upgrading, loadPersistedStateSync ignores the old field and returns an empty map, so the first poll treats every historical comment as unseen and re-fires onComment for all of them. That can spam AI replies or other automations. The loader should accept both the new and legacy keys (converting the stored last ID into a singleton set) so upgrades don’t retrigger past comments.

[P1] Migrate persisted PR watcher state

Similarly, the PR watcher now reads lastCommentIdsByPr but previous releases persisted lastCommentIdByPr. Ignoring the legacy key causes the state to be empty when upgrading, so the next poll reports all existing PR comments as new. That can double-send replies or re-run expensive processing. loadPersistedStateSync should fall back to lastCommentIdByPr and convert the stored max ID into a set, ensuring older cache files remain valid.
