Summary

What:

• Add dead-letter recovery that stops failed issue-tracking passes while keeping completed issue changes.
• Record incomplete issue tracking without changing the build's validation outcome.

Why:

• Unblock later builds when issue tracking exhausts normal retries. Today the unfinished pass remains saved, so later notifications try to resume the same failed work. Recovery needs to stop that pass without throwing away issue changes that already succeeded.
• Keep delayed workers from changing issue state after recovery. Simply clearing progress would let a paused worker write an old opening or closing after a newer build has run. Recovery protects the current issue and retains its history before allowing newer work through.

Test Plan

• Add unit tests.
• Verify recovery progress persists against a real MySQL database.

Revert Plan

• Revert this PR before enabling consumption. If already enabled, stop consumers and reconcile recovery progress before rolling back so an older consumer does not resume abandoned work.
