* Holds Mesh Beacon invitations received during this app session. Beacons are advisory, ephemeral, zero-hop

* advertisements from other meshes — not messages or contacts — so they're kept in memory only (capped, no persistence)

* and naturally age out on app restart. Consumed by the Discovery surface, which presents them for the user to Discover

* / Join / Dismiss. Room persistence can be added later if users want invitations to survive restarts.
