var doctorCmd = &cobra.Command{
	Use:   "doctor [path]",
	Short: "Check beads installation health",
	Long: `Sanity check the beads installation for the current directory or specified path.

This command checks:
  - If .beads/ directory exists
  - Database version and migration status
  - Schema compatibility (all required tables and columns present)
  - Whether using hash-based vs sequential IDs
  - If CLI version is current (checks GitHub releases)
  - If Claude plugin is current (when running in Claude Code)
  - Multiple database files
  - Multiple JSONL files
  - Daemon health (version mismatches, stale processes)
  - Database-JSONL sync status
  - File permissions
  - Circular dependencies
  - Git hooks (pre-commit, post-merge, pre-push)
  - .beads/.gitignore up to date
  - Metadata.json version tracking (LastBdVersion field)

Performance Mode (--perf):
  Run performance diagnostics on your database:
  - Times key operations (bd ready, bd list, bd show, etc.)
  - Collects system info (OS, arch, SQLite version, database stats)
  - Generates CPU profile for analysis
  - Outputs shareable report for bug reports

Export Mode (--output):
  Save diagnostics to a JSON file for historical analysis and bug reporting.
  Includes timestamp and platform info for tracking intermittent issues.

Examples:
  bd doctor              # Check current directory
  bd doctor /path/to/repo # Check specific repository
  bd doctor --json       # Machine-readable output
  bd doctor --fix        # Automatically fix issues (with confirmation)
  bd doctor --fix --yes  # Automatically fix issues (no confirmation)
  bd doctor --fix -i     # Confirm each fix individually (bd-3xl)
  bd doctor --dry-run    # Preview what --fix would do without making changes
  bd doctor --perf       # Performance diagnostics
