Problem

On bdon.moe's story player, the music volume slider also turns down (and the music mute silences) the voices of the
linkstory episodes ADV 10579–10608 (e.g. https://bdon.moe/en/tools/story-player?story=10579).

Their episodes' -Sound rows put the voice cues on Bgm (_category 0); every other episode has Voice (2):

ADV	asset	voice _category
10570–10578	adv_script_{nagi,mahoro,houka}_…_linkstory_*	2
10579–10608	adv_script_{raika,miku,yomogi,chieri,shizuku}_…_linkstory_*	0
10609–	tutorial, home	2

Audio.play routes a cue to the bus of its row's category, so these voices played on the Bgm bus.

Change

• tryPlayVoice (Talk and Voice rows, and the simple player) plays every voice on the Voice category whatever its
  row says, marked as a deviation in the comment.
• Audio.play / SilentAudio.play take an optional category overriding the resolved cue's; without it they play
  as before (BGM and SE unchanged).
• docs/story.md lists the departure under Fidelity.

Checks

• npm test (670 pass), npm run lint, npm run typecheck, npm run contract:check after a build.
• New tests: the override's bus and stopAll in engine-audio.test.mjs (Audio and SilentAudio); the Voice row's
  category in story-feature-voice.test.mjs.
• On the published episode data of ADV 10579: adv_voice_linkstory_raika_miku_10579_001 (row Bgm) plays on Voice;
  sound_bgm_adv_cafe_time stays on Bgm.

Superseded by #34. The cue sheet of these voices (adv_voice_linkstory_*) puts every cue in the CRI categories Voice/VoiceConfig, and the volume of a CRI category reaches a cue through its sheet's categories; the sound row's _category only decides what a category stop and a BGM crossfade reach. #34 routes the bus by the sheet's categories and leaves the row's category for stops, so a Bgm row still fades its voice out.
