Migration 026_additional_indexes adds 5 indexes identified during schema review (bd-h0we): - idx_issues_updated_at: For GetStaleIssues date filtering - idx_issues_status_priority: For common list query patterns - idx_labels_label_issue: Covering index for label lookups - idx_dependencies_issue_type: For blocked issues queries - idx_events_issue_type: For close reason queries These indexes improve query performance for common operations, particularly at scale (10K+ issues). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
