chore: disable Bevy default features to drop unused audio stack

Browse Source

Closes Quat investigation #2. The project uses kira for audio
(cpal 0.17 + alsa 0.10), but Bevy's default feature set still pulled
bevy_audio → rodio → cpal 0.15 + alsa 0.9 + symphonia codecs — about
50 transitive crates the binary never executes.

Workspace Cargo.toml's bevy entry now declares default-features =
false plus an explicit allow-list of the features actually used
(default_app subset + default_platform desktop subset + common_api +
2D + UI rendering). The list is derived analytically from the leaves
of Bevy 0.18's 2d and ui meta-features; built cleanly on the first
try with no missing-symbol errors.

Features intentionally omitted vs Bevy default:
- bevy_audio (kira handles audio directly)
- bevy_animation (custom CardAnimation, not Bevy's)
- bevy_gilrs, bevy_gizmos, bevy_picking variants, bevy_post_process,
  scene, hdr, sysinfo_plugin (none used)
- webgl2, web, android-* (desktop-only; solitaire_wasm is Bevy-free
  and uses wasm-bindgen + solitaire_core directly)
- wayland (X11 chosen; Wayland can be added later if requested)

Dependency-tree size for solitaire_app drops from 628 unique crates
to 577 (-51). Verified gone: bevy_audio, rodio, cpal 0.15. The
remaining cpal 0.17 and symphonia 0.5 are pulled by kira, not Bevy.

solitaire_wasm needed no changes — it doesn't depend on bevy.

All 1134 tests pass; clippy clean.
