Add quick-add feature with improved workflows (#802)

* Changes from feature/quick-add

* feat: Clarify system prompt and improve error handling across services. Address PR Feedback

* feat: Improve PR description parsing and refactor event handling

* feat: Add context options to pipeline orchestrator initialization

* fix: Deduplicate React and handle CJS interop for use-sync-external-store

Resolve "Cannot read properties of null (reading 'useState')" errors by
deduplicating React/react-dom and ensuring use-sync-external-store is
bundled together with React to prevent CJS packages from resolving to
different React instances.
