[0.9.1] FORK_IA_UX: Fase 2 (invite) — invite a contact to a Karvan room by feed id over SSB

Browse source 
Reuses Oasis's own private-message invite pattern (like the industry module:
pmModel.sendMessage([feed], 'KARVAN_INVITE', '... -> /karvan/<id>')), so the invite
lands in the contact's inbox with a link — no new SSB code, no touching the SSB
startup. Joining a room by link adopts a local mirror (karvanModel.adoptRoom, the
id is the capability). Real-time cross-device signaling (media/text sync between
the two mirrors) is the remaining Fase 2 piece (muxrpc ephemeral), deferred.
Verified single-node: invite publishes to the inbox, validation, adopt, form; 13/13
model tests (added adoptRoom).
