Subject: [PATCH] fix(voice): skip Burble auto-start under WebDriver browsers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Lands the console-errors slice (Group C) of #122.

`Main.res:162` calls `VoiceBridge.startVoice` unconditionally on game
startup, which opens a `ws://localhost:6473/voice` Phoenix WebSocket via
BurbleAdapter → PhoenixSocket. When the Burble voice server isn't
running (CI runners, headless test environments, any user who doesn't
have it installed), the browser logs five `WebSocket connection failed:
net::ERR_CONNECTION_REFUSED` messages to `console.error` as Phoenix
retries. That's what `tests/game-loads.spec.js:47` catches in chromium-1080p.

The browser-native WebSocket error fires before any app-level error
handler can intercept it, so suppressing it after the fact isn't an
option — the only fix is to not open the socket.

Gate auto-start on `navigator.webdriver === true`. Playwright, Selenium,
and similar automation always set this to true; real user browsers
leave it false. Result:

- Local dev / real browsers: voice starts as before
- Playwright tests: voice startup is skipped; no console errors
- Burble server actually running: still works in real browsers; tests
  unaffected (they never expect voice in CI anyway)
