Replace the single shared face.png placeholder with 52 individual card
face images (120×168 px each), generated by the updated gen_art tool:
- solitaire_assetgen: add ab_glyph dep; rewrite gen_art to render each
card with FiraMono rank characters, programmatic suit symbols (heart,
spade, diamond, club drawn via circles/triangles), and standard pip
layout for numbered cards (A–10) plus large face letter for J/Q/K.
- CardImageSet: replace single `face` handle with `faces: [[Handle; 13]; 4]`
indexed by [suit][rank].
- card_sprite(): select the per-card face image by suit/rank indices.
- spawn/update_card_entity: suppress Text2d overlay when PNG faces are
loaded (rank/suit baked into image); keep overlay in solid-colour
fallback for tests.
- gen_sfx.rs: rename `gen` variable to `make` (reserved keyword in 2024).

- New solitaire_assetgen crate with gen_sfx binary: synthesizes
five 44.1kHz mono 16-bit PCM WAVs (flip/place/deal/invalid/fanfare)
from an LCG noise source + sine/square synths. Output committed
under assets/audio/.
- AudioPlugin (engine): embeds the WAVs via include_bytes!, decodes
once with kira::StaticSoundData, plays on Draw / Move / NewGame /
GameWon events. card_invalid is loaded but unused — wiring it
needs a MoveRejectedEvent.
- AudioManager kept on the main thread (NonSend) since cpal is !Send
on some platforms; degrades gracefully if no audio device present.
