Improve test coverage to 57.7% (+13.5%)

Added comprehensive test coverage for previously untested commands:
- version_test.go: Plain text and JSON version output
- list_test.go: All filter operations and label normalization
- export_test.go: JSONL export with labels & dependencies
- stale_test.go: Duration formatting and stale issue detection
- comments_test.go: Comment management and error handling
- delete_test.go: Batch deletion helpers
- metrics_test.go: RPC metrics recording and snapshots

Coverage improvement:
- Overall: 44.2% → 57.7% (+13.5%)
- cmd/bd: 17.9% → 19.8% (+1.9%)
- internal/rpc: 45.2% → 45.8% (+0.6%)

All tests passing with no new linter warnings.
