📝 WalkthroughWalkthroughAdds a new React Router frontend example with LiveKit integration (token endpoint, UI, routes, styles, build/config), and updates backend worker/session logic to support spawn-safe provider objects, provider pickling, and merged turn_handling; also updates docs, tests, and dependencies to use OpenAI-based provider configuration.

Inline comments:
In `@examples/frontend/app/app.css`:
- Around line 3-5: The stylelint config extends stylelint-config-standard-scss
which will flag Tailwind v4 at-rules like `@theme` as unknown; update
.stylelintrc.json to override the scss/at-rule-no-unknown rule so it ignores
Tailwind directives (e.g., add scss/at-rule-no-unknown with ignoreAtRules
including "theme", "utility", "variant", "apply") or disable that rule entirely
to prevent editor/CI failures when encountering `@theme` in app.css.
In `@examples/frontend/app/components/demo-call-page.tsx`:
- Around line 32-36: The startCall flow is vulnerable to re-entrancy and stale
async updates after unmount; add a mounted flag and an in-flight guard to
prevent parallel invocations and post-unmount setState calls: introduce a ref
like isMountedRef updated in the existing useEffect cleanup that calls
disconnectFromRoom(), check isMountedRef.current before any state updates (e.g.
the phase state updates around startCall and subsequent async steps), and add an
isStarting/inFlight ref guard around the startCall function to early-return if a
start is already in progress; ensure any async callbacks (the blocks at lines
noted that update state after awaits) verify isMountedRef.current and clear the
in-flight flag on all paths (success/error) to avoid stale updates or racing
calls.
In `@examples/frontend/app/routes/api.token.ts`:
- Around line 22-24: The action handler parses request.json() directly which can
throw on malformed JSON and convert what should be a 400 client error into an
unhandled 500; wrap the parse in a try/catch and on any JSON parse error return
a 400 response (with a clear message) before running validation like
isDemoVariant; apply the same change to the other request.json()-parsing handler
in this file so both handlers explicitly handle malformed JSON and then validate
variant.

issues at runtime.
