list_voice_clips now enumerates every spoken-line category so the standalone audio player covers them all — bound movie voices (\Movie\), in-mission radio (\Voice\, \etc\), and mission briefings (\Briefing\, whose BR<NN>_<MM> names lack "VOICE"); music (BGM_*) stays excluded.
Viewer voice-library fixes: invalidate the library when a new game source loads, and don't latch an empty result as "loaded" (sounds.tbl always has thousands of clips, so empty = a failed read) so re-opening the menu retries.
Voice decode reverted to the first sub-wave (base behaviour): a naive multi-sub-wave concat produced the wrong track for RT movies. The per-sub-wave splitter (to_xma_riffs) is kept + documented for the eventual real fix, which needs ground-truth playback instrumentation to resolve segments-vs-takes-vs-timecode placement.
