Rename several classes/behaviors to factory-style creators and adapt
call wiring and tests accordingly:
- Replace ConnectionManager class with createConnectionManager$ which
returns transports$, connectionManagerData$, connections$
- Convert MatrixLivekitMerger to createMatrixLivekitMembers$
(matrixLivekitMerger$)
- Rename sessionBehaviors$, localMembership$, localTransport$ to
createSessionMembershipsAndTransports$, createLocalMembership$,
createLocalTransport$
- Adjust participant types and hook up connectOptions$; expose join via
localMembership.requestConnect
- Update tests to use the new factory APIs
- Replace MatrixLivekitItem with MatrixLivekitMember, add displayName$
and participantId, and use explicit LiveKit participant types
- Make sessionBehaviors$ accept a props object and return a typed
RxRtcSession
- Update CallViewModel to use the new session behaviors, rebuild media
items from matrixLivekitMembers, handle missing connections and use
participantId-based keys
- Change localMembership/localTransport to accept Behavior-based
options, read options.value for enterRTCSession, and fix advertised
transport selection order
- Update tests and minor UI adjustments (settings modal livekitRooms
stubbed) and fix JSON formatting in locales
Remove preferStickyEvents and multiSfu in favor of a MatrixRTCMode
enum/setting (Legacy, Compatibil, Matrix_2_0). Move session join/leave,
track pause/resume, and config error handling out of CallViewModel into
the localMembership module. Update developer settings UI, i18n strings,
and related RTC session helpers and wiring accordingly.
While we still ought to eventually port these tests in some way, the presence of these empty test files is causing a Vitest failure, so it's easiest to just let them go and refer to Git history when we do want to reference them next.
