The SDK now takes `publish` requests and audio output control directly
in the main options object, removing the separate `LocalMediaInputs`
type. Audio output device selection moves from a reactive behavior to an
imperative method on `MatrixRTCClient`, giving hosts direct control over
when devices switch.
One way to put media on the session: publish(request) resolves with the local track once LiveKit has it, and unpublish(id) removes it. A request names a source with its device, processor and capture settings, so CaptureSettings on the client options goes, as do setMicrophoneEnabled and setCameraEnabled on the client and the four screen share fields on the local member; sharing is tracks$ having a screenShare track, and a capture failure rejects the promise. LocalMediaInputs becomes the list of initial requests, which also become the room defaults so that one permission prompt covers microphone and camera. The publisher keeps the requests across a reconnection and republishes what is not muted. The harness gains a Share screen button.

Our own tracks are LocalAudioMediaTrack and LocalVideoMediaTrack, with setEnabled and setDevice, and on video facingMode$, switchFacingMode and setProcessor. switchCamera on the local media goes, as do the device and processor behaviors in LocalMediaInputs: a host calls the track when its setting changes instead of the SDK watching behaviors it does not own. The input device ids and the processor stay as initial values for the tracks created at the join. setMicrophoneEnabled and setCameraEnabled stay for the case of no track yet.

Update the public API to export the primitives and operators the call
model needs, and change `LocalMediaInputs` from observable flags to
immediate booleans with imperative setters. Add session timings, media
quality and capture settings as configuration options, and allow the
host to override the transport discovery with explicit URLs.
Set up `sdk/` as a package shaped exactly like `component/`: its own
package.json with peer dependencies, the pnpm workspace marker so a host can
install it as a git dependency, a build tsconfig for type emission, and a vite
lib config with an externals list that `pnpm lint:externals` now checks for
both library builds.
The package holds only the interface for now. `createRtcSession` returns an
empty object; `RtcSession`, `RtcMember`, `MemberMedia` and `TransportMetadata`
are the contract Element Call's `CallViewModel` will be rebuilt on (see
sdk-plan.md). The shared primitives are re-exported from `src` until the first
implementation slice moves them.
`sdk/dev` is the smallest consumer of the SDK: a plain page that logs in, joins
a room and renders one tile per member, served by `pnpm dev:sdk` on port 3002.
Playwright starts it as a third web server, and `playwright/sdk/smoke.spec.ts`
has two browsers join one session. It fails on the status line with the SDK's
own error until there is an implementation behind the interface.
