test(daemon): add unit tests for daemon package (gt-99a)

Add comprehensive unit tests for:
- Config and state serialization (DefaultConfig, LoadState, SaveState)
- Session name pattern matching (isWitnessSession)
- Lifecycle request parsing (parseLifecycleRequest)
- Identity to session mapping (identityToSession)

Tests document a bug where parseLifecycleRequest always matches 'cycle'
because "LIFECYCLE:" prefix contains "cycle". Filed as gt-rixa.
