Space voice channels send room-level RTC notifications (m.mentions.room)
whenever any member joins. Previously this triggered the incoming call
ring modal for every member of the space, as if they were personally
being called.
Fix: before setting callInfo, check whether the room is a DM (in
mDirectAtom) or a private non-space group (invite/knock/restricted join
rule AND no m.space.parent state event). Space channels and public rooms
are excluded — joining them should never ring other members.
Added JoinRule to the matrix-js-sdk import. Added directs to the
useCallback dependency array so the closure sees the current DM set.
