refactor(RoomStore): inline the state initializer into createRoomStore

[diegolmello]

Proposed changes

Inline the private curried createRoomState initializer into the exported createRoomStore. The public factory now calls createStore directly with the same initializer body, and the defaults (EMPTY_ROOM for the initial room, null for the room user id) move to its parameter destructuring. The unused StateCreator import is removed.

One file, mechanical move only. The exported signature, state shape, action closures, retry loop, cancellation and read receipt timing are unchanged.

Issue(s)

Follow-up to #7482; targets its native-34-roomview-hooks branch.

How to test or reproduce

• pnpm oxfmt --check and pnpm oxlint on the changed file pass (one pre-existing complexity warning in the untouched loadRoom).
• pnpm tsc --noEmit is clean.
• TZ=UTC pnpm test for the RoomStore and useRoomInit suites passes: 3 suites, 54 tests.
• No remaining references to createRoomState or StateCreator in app/.

Further comments

Existing tests are unchanged. An independent review confirmed the initializer body is identical modulo indentation and that no evaluation timing changed.

Summary by CodeRabbit

• Refactor
  • Simplified room store setup while preserving existing room initialization, retry, membership, join, and resume behavior.
  • Added default handling for room and user values when creating the room store.

Walkthrough

The room store removes the standalone state factory. createRoomStore now creates the complete Zustand state inline and supplies defaults for initialRoom and roomUserId. Existing room initialization, retry, membership, join, and resume behavior remains in place.

Align the factory parameter type with the initialRoom default.

createRoomStore requires initialRoom, while the default only applies when the property is absent at runtime. The production caller always supplies it through IRoomScreenInput; IRoomStoreInitParams is unrelated. If createRoomStore({}) should be supported, make initialRoom optional. Otherwise, remove the default.
