* fix(hyperframes-media): surface the real reason a TTS line failed
synthesizeHeygen() swallowed every failure into a bare { ok:false }: a thrown
HTTP error (e.g. 402 plan_upgrade_required from heygenJSON) was caught and
discarded, a missing audio_url / failed audio fetch / failed transcode all
returned nothing. audio.mjs then logged 'TTS failed — omitted' for every line
with zero detail, so the actual cause took a hand-rolled repro to find.
Each failure path now returns an { error } string (the caught message, the HTTP
status, or the specific stage that failed), and audio.mjs appends it to the
anomaly. The subprocess providers (elevenlabs/kokoro) get the same treatment via
a shared synthResult() helper. synthesizeHeygen takes an injectable deps arg so
the failure paths are unit-tested (thrown 402, non-ok fetch, missing audio_url).
* fix(media-use): report wav transcode failures accurately
* chore: regenerate skills manifest
The ElevenLabs provider spawns a Python helper that writes straight to wavAbs
via a bare open(), which (unlike heygen/kokoro) never creates the parent dir —
so on a fresh project the save throws ENOENT and the line is silently dropped
as 'TTS failed - omitted'. mkdir -p the dir first, guarded so a mkdir failure
(EACCES/EROFS) returns { ok:false } like the rest of the branch rather than
throwing. (Migrated from #1960, whose skills/hyperframes-media path was retired
into skills/media-use; the bug moved with it.)
