v0.1.1: fix .app bundle PATH for pyenv/nvm, detect yt-dlp pot-provider plugin

- fix_path_env() now adds ~/.pyenv/shims (with PYENV_ROOT) before
  Homebrew paths so pyenv-managed yt-dlp (with pip-installed plugins)
  takes priority over Homebrew's bare yt-dlp binary
- Also handles ~/.nvm, ~/.deno/bin, ~/.cargo/bin for broader coverage
- check_pot_plugin uses lightweight 'yt-dlp -v' instead of network
  simulation for reliable plugin detection
- Bump version to 0.1.1
