- Planned and documented the CLI overhaul for hierarchical YAML configuration and new output modes (`plans/cli-overhaul-config.md`).
- Committed research on transcription optimization, previous implementation plans, and synchronized `TASKS.md`.
- Implemented the CLI overhaul, standardized core class naming to `HarpDaemon`/`HarpConfig`, fixed all associated tests, and released version `v0.4.0`.
- Started implementing high-speed concurrent transcription architecture.
- Released v0.5.0 with local-first Whisper transcription, optimized CLI imports, and refined model management using subdirectories.
- Improved unit test isolation by mocking hardware-dependent libraries (sounddevice, uinput) to ensure CI/CD stability.
