* Add bd doctor command for installation health checks Implements a comprehensive health check command similar to claude doctor that validates beads installation and provides actionable recommendations. Features: - Installation check (.beads/ directory exists) - Database version verification (compares with CLI version) - ID format detection (hash-based vs sequential) - CLI version check (fetches latest from GitHub) - Storage type detection (SQLite vs JSONL-only mode) - Tree-style output with color-coded warnings - JSON output for scripting (--json flag) - Actionable fix recommendations for each issue Implementation improvements: - Status constants instead of magic strings - Semantic version comparison (fixes 0.10.0 vs 0.9.9 edge case) - Documented defer pattern for intentional error ignore - Comprehensive test coverage including version comparison edge cases - Clean integration using slices.Contains for command list Usage: bd doctor # Check current directory bd doctor /path/to/repo # Check specific repository bd doctor --json # Machine-readable output * Simplify bd doctor documentation in README Reduce verbose health check section to 2 lines as requested. * Fix bd doctor to handle JSONL-only mode for ID format check When no SQLite database exists (JSONL-only mode), skip the ID format check instead of showing an error. This prevents the confusing 'Unable to query issues' error when the installation is actually fine.
