PR Lifecycle & Auto-Reply
Full pull request lifecycle management with GitHub comment sync, inline review threads in the diff viewer, and automatic AI replies to PR conversations.

Features
- PR lifecycle management — track PRs from creation through review, addressing feedback, and merge, with real-time status in the activity timeline
- GitHub PR comments in diff viewer — review comments from GitHub are displayed inline alongside the code diff for full context
- Auto-reply for PR comments — SUSTN automatically responds to conversational PR comments using a unified Claude session, with a per-repo toggle to enable or disable
- React error boundaries — component-level crash isolation prevents a single UI failure from taking down the entire app
Improvements
- Replaced heuristic comment classifier with a unified Claude session for more accurate review vs. conversational comment handling
- Compact single-card design for PR review comment threads with tighter spacing
- PR lifecycle events now render in the activity timeline with clear status indicators
Fixes
- Fixed
nullcomment_idin Claude review responses causing failed comment syncs - Fixed comment classification so conversational comments are processed without requiring a formal review cycle
- PR comments now always sync correctly — removed stale filter that was hiding the bot's own replies
- Bypassed worker queue for
engine_address_reviewto call Claude directly, preventing stuck addressing state
