chore: bump version to 0.2.5 [skip ci]

- Exclude ctranslate2.converters from PyInstaller bundle — these modules
  import torch at module level causing circular import crashes, and are
  only needed for model conversion (never used at runtime)
- Defer all heavy ML imports to first handler call instead of startup,
  so the sidecar can send its ready message without loading torch/whisper
