When daemon detects multiple .db files (after filtering .backup and vc.db),
it now writes detailed error to .beads/daemon-error file before exiting.
The error file is checked and displayed when:
- Daemon discovery fails to connect
- Auto-start fails to yield a running daemon
- User runs 'bd daemons list'
This makes the error immediately visible without requiring users to check
daemon logs.
Changes:
- cmd/bd/daemon.go: Write daemon-error file on multiple .db detection
- internal/daemon/discovery.go: Read and surface daemon-error in DaemonInfo.Error
- cmd/bd/main.go: Display daemon-error when auto-start fails

- Added tests for extractIssuePrefix, loadIssuesFromJSONL, detectPrefix, writeIssuesToJSONL
- Added tests for walkWithDepth depth limiting and hidden directory skipping
- Added tests for DiscoverDaemons registry and legacy discovery paths
- Improved test coverage for cmd/bd and internal/daemon
- Created global daemon registry at ~/.beads/registry.json
- Daemons auto-register on start, unregister on graceful shutdown
- DiscoverDaemons() now uses registry instead of filesystem scan
- Instant daemon discovery (35ms vs indefinite hang)
- Auto-cleanup of stale registry entries
- Full test coverage
