Code Review Summary — PR #1035: Sentry Error Intelligence Dashboard

This PR adds a new "Sentry Error Intelligence" dashboard to the analytics template with rich error analysis, escalation detection, and enhanced Slack/GitHub integration. The feature includes:

• New sentry-errors dashboard with top-10 error analysis, escalation detection, and related error grouping
• Sentry org slug support via new data source field for proper multi-org configuration
• Enhanced Slack search with optional user-token support and intelligent fallback (fuzzy search with bot token)
• GitHub blame integration exposing commit history and contributor context for errors
• Thread enrichment fetching full Slack conversation context alongside search results

Architecture Assessment: The implementation is well-structured with proper separation of concerns (UI components, actions, server-side integrations), appropriate credential handling, and good error fallback patterns. Type safety is solid throughout.

Risk Classification: Standard risk (analytics feature addition, no breaking API changes, no database schema modifications).

Key Findings

Critical Issues: 🔴

• Missing function import breaks Slack user-token search (ReferenceError at runtime)

Should-Fix Issues: 🟡

• GitHub blame feature shipped but not integrated into the dashboard UI
• Slack secondary-workspace searches use wrong user token credential
• Sensitive Slack search content and queries leaked to server logs
• Slack URL matching has trailing-slash normalization issue
• Unused Sentry stats query adds unnecessary API overhead

Positives: ✅

• Proper credential scoping and access control
• Well-designed async error handling and fallbacks
• Correct React patterns (memoization, hook dependencies)
• Thoughtful API integration (Slack, GitHub, Sentry)

🧪 Browser testing: Will run after this review (PR touches UI code)
