chore: git hygiene — enforce LF, drop dead .gitattributes/.gitignore rules

- .gitattributes: 'text=auto eol=lf' so files are stored and checked out as LF
  on every OS (no more CRLF churn on Windows, regardless of core.autocrlf);
  mark common binaries; keep .bat/.cmd as CRLF.
- Remove the stale Git LFS rule for modules/vlc-player (that module no longer
  exists and no LFS objects are tracked).
- .gitignore: stop ignoring bun.lock (it's committed and checked by the lockfile
  workflow), and replace the dead/duplicate per-module build paths (player,
  hls-downloader, sf-player, music-controls, duplicate mpv-player) with a single
  modules/*/android/build/ glob.
- Renormalise the one CRLF-stored file (crowdin.yml) to LF (EOL only).
