Harden installer icon + NSIS rebuild path

- Regenerate icon.ico with classic BMP entries (16/32/48) — PNG-compressed
  ICO entries can fail NSIS' icon loader on some builds
- CI copies assets/textures/icon.ico onto the packaging path right before
  makensis, removing any stale/missing-copy failures
- Recreate v0.2.1 tag after this fix
