docs: fix completion links and update manual completions

- Fix README to link to installation guide instead of completions directory
- Update installation.md to reference correct completion filenames
- Add new v1.34.0 CLI options to manual bash/zsh completions:
  - --input-list
  - --replaygain
  - -as/--audio-streams
  - --audio-default-only
  - --keep-other-audio

The manual completions are maintained separately from the shtab-generated
versions to provide better user experience.
