Enables preview of operations without making changes, useful for
understanding what would happen before committing to a full sync.
Ingest dry-run (--dry-run flag):
- Shows resource type, sync mode (full vs incremental), project list
- Per-project info: existing count, has_cursor, last_synced timestamp
- No GitLab API calls, no database writes
Sync dry-run (--dry-run flag):
- Preview all four stages: issues ingest, MRs ingest, docs, embed
- Shows which stages would run vs be skipped (--no-docs, --no-embed)
- Per-project breakdown for both entity types
Stats repair dry-run (--dry-run flag):
- Shows what would be repaired without executing repairs
- "would fix" vs "fixed" indicator in terminal output
- dry_run: true field in JSON response
Implementation details:
- DryRunPreview struct captures project-level sync state
- SyncDryRunResult aggregates previews for all sync stages
- Terminal output uses yellow styling for "would" actions
- JSON output includes dry_run: true at top level
Flag handling:
- --dry-run and --no-dry-run pair for explicit control
- Defaults to false (normal operation)
