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).
