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.)
