tajniak81andClaude Opus 5.5 41f800ab0b Mobile: voice and video calls (MatrixRTC with LiveKit)
Calls the way the web client and Element Call do them, with the same
events, so the three can share a call. The famedly SDK's own group calls
use com.famedly.call.member events, which the others don't read, so this
is written against the matrix-js-sdk wire format instead (lib/matrix/
calls.dart):

- Membership: org.matrix.msc3401.call.member state, key
  _@user:server_DEVICE_m.call, with the legacy session fields the js-sdk
  sends (application m.call, call_id "", membershipID, expires,
  focus_active, foci_preferred). An empty delayed copy (MSC4140) is
  scheduled first and pushed back every 5 s; leaving sends the empty
  state and cancels it.
- Media: a LiveKit token from the JWT service (the call's, else the
  homeserver's rtc/transports or .well-known rtc_foci) for an OpenID
  token; livekit_client connects.
- Encrypted rooms: a random 16-byte key per device, sent to every other
  device in the call over encrypted to-device
  io.element.call.encryption_keys, keys from others applied per LiveKit
  identity (@user:server:DEVICE); per-participant keys, no ratcheting,
  HKDF, like the web client's livekit-client.
- Ringing: a call started in a room of two sends a ring notification
  (MSC4075); the other side gets an incoming-call card and an insistent
  ringtone notification (full screen on a locked phone), declines with
  MSC4310 or answers by joining. The caller gives up after a minute or on
  a decline.
- UI: voice and video buttons in the room header, a call screen (the
  other person large and you in the corner, or a grid; mute, camera, flip,
  leave), a Join banner and a room-list marker for calls going on.

Not tested end to end yet: it needs a LiveKit SFU and JWT service.

README: replies, reactions, threads, spaces, QR verification, sliding
sync and calls.
