Subject: [PATCH] feat(meetingrooms): show parent MeetingSpace link on
 kind:30313
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A NIP-53 kind-30313 [MeetingRoomEvent] references its parent kind-30312
[MeetingSpaceEvent] via the standard `["a", "30312:<host>:<d>"]` tag.
Without surfacing it, a meeting card in a feed lost the context of
which Nest the meeting belonged to — users couldn't tell if "Office
Hours Q3" lived inside their company nest or someone else's.

Render a small "In <Space Name>" label above the meeting's title
inside [RenderMeetingRoomEventInner]:

  - Resolves the parent address via `MeetingRoomEvent.interactiveRoom()`
    → `MeetingSpaceTag.address`. Bails when the address points at
    something other than kind:30312 (no broken links).
  - Loads the parent through the existing `LoadAddressableNote`
    helper. When the kind:30312 hasn't propagated to LocalCache yet,
    the row falls back to a generic "In a Nest" label and tapping
    routes through the standard `routeFor` thread path which
    auto-fetches.
  - Tap navigates to the parent space's thread view via `routeFor`
    + `nav.nav` — the same path Discovery / NoteCompose use for
    quote-into-thread navigation.

Two new strings:
  - meeting_room_in_space ("In %1$s")
  - meeting_room_in_space_unknown ("a Nest" — fallback when the
    parent space isn't yet resolvable)
