media-use tts.mjs leaves one hf-txt-* temp directory per synthesized line #5466

Environment: skills installed from heygen-com/hyperframes on 2026-10-10, CLI 0.8.145.

skills/media-use/audio/scripts/lib/tts.mjs → writeTmpText() creates mkdtempSync(join(tmpdir(), "hf-txt-")) for every synthesized line (ElevenLabs and Kokoro paths) and never removes it. A 40-line voiceover leaves 40 directories in the temp folder per run.

Fix: remove the directory after the synthesis call returns (e.g. rmSync(dirname(p), { recursive: true, force: true }) in a finally), as transcodeToWav() already does for its own temp dir.
