PR Summary

TTS: Edge provider + fallback flow

  • Add edge TTS via node-edge-tts; defaults to Edge when no OpenAI/ElevenLabs keys; new config (messages.tts.edge.*) and schema/types
  • Implement provider resolution (getTtsProvider) preferring OpenAI→ElevenLabs→Edge; expose resolveTtsProviderOrder and isTtsProviderConfigured
  • Support Edge output formats with extension inference and retry to MP3 on format errors; preserve voice-note compatibility signal
  • Update /tts command UX (status/provider, fallbacks) and gateway RPC (tts.status|setProvider|providers) to include Edge
  • Expand tests for provider selection, Edge output format, directive parsing, and summary flow; add node-edge-tts dependency
  • Docs: TTS guide for Edge behavior/config/output caveats; minor Google Chat docs markup fix; changelog entry

docs/tts.md
Edge TTS uses Microsoft Edge's online neural TTS service via the `node-edge-tts`
library. It's a hosted service (not local), uses Microsoft’s endpoints, and does
not require an API key. `node-edge-tts` exposes speech configuration options and
output formats, but not all options are supported by the Edge service. citeturn2search0

Citation artifacts left in documentation

Low Severity

The documentation contains citation artifacts like citeturn2search0, citeturn0search3, citeturn1search0, and citeturn1search1 that appear to be leftover from an AI-assisted writing tool. These meaningless strings appear in user-facing documentation and should be removed. They appear after sentences on lines 25, 30, 297, 298, and 300.
