auto-claude: 201-bug-pr-review-logs-and-analysis (#1730)

* auto-claude: subtask-1-1 - Add debug logging to trace PR review execution and log collection

- Added debug log in PRLogCollector constructor showing creation with log path
- Added debug log in processLine() showing each call with phase info
- Added debug log in save() showing save operations with log path and phase summary

This will help trace PR review execution and identify log collection issues.

* auto-claude: subtask-1-2 - Verify log file creation and contents during review execution

- Analyzed PRLogCollector class implementation
- Confirmed log file path: .auto-claude/github/pr/logs_${prNumber}.json
- Verified debug logging is functional (createContextLogger)
- Created verification guide (VERIFICATION-LOG-CREATION.md)
- Created verification script (verify-log-creation.sh)
- Created summary document (SUBTASK-1-2-SUMMARY.md)
- Updated implementation_plan.json (status: completed)
- TypeScript compilation verified (no errors)

Findings: Log file creation mechanism is correctly implemented.
Manual PR review execution needed to confirm runtime behavior.

* auto-claude: subtask-1-3 - Test frontend polling mechanism and log loading

* auto-claude: subtask-2-1 - Add push-based IPC events for PR review log updates

Implemented Fix 3 from INVESTIGATION.md:
- Added GITHUB_PR_LOGS_UPDATED IPC channel constant
- Modified PRLogCollector to accept BrowserWindow and emit events on save()
- Events notify renderer of log updates with phase status and entry count
- Enables real-time log visibility without relying solely on polling

Files modified:
- apps/frontend/src/shared/constants/ipc.ts (new IPC channel)
- apps/frontend/src/main/ipc-handlers/github/pr-handlers.ts (PRLogCollector class)

* auto-claude: subtask-2-2 - Add fallback mechanism to load logs after review completes

- Add useEffect hook that triggers when review completes successfully
- Check if logs need to be loaded (missing or from different review type)
- Load logs with 500ms delay to ensure backend has written them
- Properly handle loading state and errors
- Ensures logs are available even if polling didn't capture them during execution

* auto-claude: subtask-2-3 - Ensure analysis results are displayed alongside lo

* auto-claude: subtask-4-1 - Remove debug console.log statements added during investigation

* auto-claude: subtask-4-2 - Add code comments explaining log collection and polling mechanism

Added comprehensive documentation for the PR review log streaming system:

Backend (pr-handlers.ts):
- Documented getPRLogsPath(), loadPRLogs(), and savePRLogs() functions
- Added detailed explanation of PRLogCollector hybrid push/pull architecture
- Explained file-based storage (every 3 entries), IPC push events, and polling fallback
- Documented save() method's two-step update mechanism (file write + IPC event)
- Added polling strategy explanation to IPC handler (GITHUB_PR_GET_LOGS)

Frontend (PRDetail.tsx):
- Added comprehensive overview of log data flow and architecture
- Documented initial load effect when logs section expands
- Explained active polling mechanism (1.5s interval) with timing rationale
- Added detailed fallback mechanism documentation for edge cases
- Documented state reset effect when switching between PRs

The comments explain:
- Why 1.5 second polling interval (balances responsiveness vs I/O)
- Why hybrid push/pull (reliability + responsiveness)
- How file-based storage enables debugging and crash recovery
- All three polling scenarios (start, active, end)
- Edge cases handled by fallback mechanism (race conditions, etc.)

* Fix PR review findings: wire up IPC push events, fix tests, remove dev artifact

- Wire up GITHUB_PR_LOGS_UPDATED IPC event end-to-end: add onPRLogsUpdated
  listener to preload API, subscribe in PRDetail for instant log refresh
- Fix IPC emission to use standard (projectId, data) pattern
- Fix runner-env-handlers test: add isDestroyed() to mock BrowserWindow
- Fix PRDetail integration test: add onPRLogsUpdated mock
- Remove verify-log-creation.sh development artifact from repo root
- Clean up console.error debug prefixes to use standard error messages

+   *    - Clears stale logs from previous reviews
+   *    - Prepares for new log stream

+   *    - Backend writes logs every 3 entries, so 1.5s polling ensures

+   *    - 500ms delay ensures backend has time to write final state
+   *
+   * 2. Follow-up Review Mismatch: User runs follow-up after initial review
+   *    - prLogs.is_followup !== reviewResult.isFollowupReview
+   *    - Need to reload logs to show correct review type

+   * 3. Component Remount: User switches away and back to the PR

+   *    - Fallback ensures logs are reloaded from disk
+   *
+   * Timing:
+   * -------
+   * - 500ms delay balances reliability vs. responsiveness
+   * - Backend typically writes logs in <100ms, but network drives,
+   *   virus scanners, or disk contention can delay writes
+   * - Delay is user-imperceptible since review is already complete

+   * - prLogs: Clears displayed log content
+   * - logsExpanded: Collapses logs section (user must explicitly expand)
+   * - Review posting state: Clears any success/error messages
