TTS Media Route Fix

Overview

Apply a production-safe patch workflow for OpenClaw installs where tts.convert and /media/tts/<id>.mp3 routing are broken or incomplete. Always back up hashed dist files before edits, patch minimally, restart gateway, and verify with authenticated range curl.

Workflow

1. Locate active hashed gateway-cli-*.js files.
2. Back up each file to *.bak before modifying.
3. Patch HTTP handler for GET/HEAD /media/tts/<id>.mp3 with auth, validation, binary output, and Range.
4. Ensure tts.convert payload returns audioUrl under /media/tts/<id>.mp3 and mp3 metadata.
5. Restart gateway.
6. Verify with Bearer-authenticated curl (including --range).
7. Confirm temporary file TTL cleanup (2–5 minutes).
