chore: bump version to 0.2.45 [skip ci]

Instead of chmod on every app start, catch EACCES (error 13) when
spawning sidecar or ffmpeg, fix permissions, then retry once:
- sidecar spawn: catches permission denied, runs set_executable_permissions
  on the sidecar dir, retries spawn
- ffmpeg: catches permission denied, chmod +x ffmpeg and ffprobe, retries

Zero overhead on normal launches. Only fixes permissions when actually needed.
