fix: Reconcile reviewer findings with PR threads (#1346)

Browse source 
* feat: reconcile reviewer findings with PR threads

* fix: harden reviewer finding reply handling

* fix: queue reviewer finding reply body

Ensure review-comment replies that arrive during an active reviewer run include the sanitized reply body in the queued reassessment prompt.

* fix: apply reviewer reply formatting

Apply the repository formatter so the reviewer reply handling fix passes CI format checks.
