refactor: rename the package from ccn-transcribe to audio-scribe

The distribution, console script and import package are now audio-scribe /
audio_scribe (src/audio_scribe). Everything named for the old project follows:

- CcnError -> AudioScribeError, and its code "ccn_error" -> "audio_scribe_error"
  (the code is never persisted, so existing job state still loads)
- CCN_LIVE -> AUDIO_SCRIBE_LIVE for the live-GPU tests
- OpenVINO kernel cache moves to <cache>/audio-scribe/ov_cache; the first run
  after upgrading recompiles kernels, and the old directory is left in place
- README, build-binary.sh, hatch/coverage config and uv.lock updated to match

Breaking: the command is now `audio-scribe`; reinstall any tool install of the
old name with `uv tool uninstall ccn-transcribe && uv tool install .`.
