Diego Rodrigues de Sa e Souza 6695cbbf7a feat: add EdgeTTS audio-tts provider (#6668) (#7605)
* feat(sse): add EdgeTTS audio-tts provider (#6668)

Registers Microsoft Edge "Read Aloud" as a new no-API-key AUDIO_SPEECH_PROVIDERS
entry — the first WebSocket-transport TTS provider in the registry. Reverse-
engineered/unofficial endpoint, same class of integration already accepted for
other "-web" style providers (chatgpt-web.ts, copilot-web.ts).

- open-sse/executors/edgeTts.ts: pure Sec-MS-GEC token construction (SHA-256
  over a public trusted-client-token + rounded Windows file-time ticks, ported
  from rany2/edge-tts drm.py), WS message framing (speech.config/ssml),
  binary-chunk demuxing, SSML building/escaping, and the WS synth call itself
  (injectable WebSocket ctor for tests, lazy `import("ws")` in production so
  it never enters esbuild's top-level CJS bundle graph). Per-client-IP
  sliding-window throttle (SlidingWindowLimiter) since there's no per-user key
  — one abusive deployment could otherwise get the shared trusted token
  rate-limited for everyone.
- open-sse/utils/publicCreds.ts: embeds the trusted-client-token via
  resolvePublicCred() (Hard Rule #11) — it's a constant hardcoded in every
  Edge build and every open-source edge-tts port, not a per-user secret.
- Extracted open-sse/utils/audioResponse.ts (shared response helpers) and
  open-sse/executors/awsPollyTts.ts (AWS Polly handler) out of
  open-sse/handlers/audioSpeech.ts to stay under its frozen file-size ratchet
  baseline while making room for the new branch — no behavior change to
  either extracted piece.
- src/app/api/v1/audio/speech/route.ts: thread the caller's IP through to the
  handler for the new throttle.

Tests: tests/unit/edgetts-provider.test.ts (23 cases) — Sec-MS-GEC determinism
and cross-check against a hand-derived reference vector, message framing,
binary demux, SSML escaping/injection-safety, registry lookup, publicCreds
shape, and the error path via an injected fake WebSocket (upstream failure ->
sanitized 502, no stack/path leak; Hard Rule #12), plus the per-IP rate limit.
No live upstream is required or used — the reverse-engineered protocol can't
be validated against real credentials, but every pure/testable seam is
covered per the TDD path in the bug/feature validation gate.

* test(mutation): register edgetts-provider.test.ts in stryker tap.testFiles (#6668)

The new provider's unit test covers a mutated module, so the strict
mutation-test-coverage gate requires it in stryker.conf.json's
tap.testFiles. Single-line addition (kept the file's existing formatting).
