Fix compilation errors in internal/daemonrunner package

Created missing files:
- logger.go: Logger type, setupLogger method, and env helpers
- signals_unix.go: Unix signal definitions (SIGTERM, SIGINT, SIGHUP)
- signals_windows.go: Windows signal definitions
- sync.go: Sync loop implementation with export/import/validation helpers

Fixed errors:
- Added missing 'version' parameter to acquireDaemonLock call
- Removed duplicate setupLock method from process.go (kept in daemon.go)
- Removed duplicate startRPCServer from daemon.go (kept in rpc.go)
- Fixed LogPath -> LogFile config field reference
- Removed unused 'io' import from process.go

Implementation notes:
- exportToJSONL: Full implementation with dependencies, labels, comments
- importFromJSONL: Placeholder (TODO: extract from cmd/bd/import.go)
- countDBIssues: Uses SQL COUNT(*) optimization with fallback
- validatePostImport: Checks for data loss
- runSyncLoop/runEventLoop: Main daemon event loops with signal handling

All packages now compile successfully with 'go build ./...'
