What

Explore public spaces. A compass button in the spaces rail opens a directory of public spaces:

• search, and read another server's directory by typing its name
• open a space to see the rooms inside before joining (/hierarchy)
• join the space, or individual rooms in it

Space context menu. Right-click a space (press and hold on mobile), modelled on Discord's server menu:

• mark as read · invite to space
• mute space · notification settings › (all / @mentions / nothing) · hide muted rooms · browse rooms
• leave space (red, with an opt-in to also leave rooms only that space holds) · copy space id

Privacy settings, per-server profile and "move to" (folders) have no Matrix equivalent and are left out.

Why / notes for review

• Joins over federation. join_room now takes via servers, which a room ID from another server's directory needs. Joins also get a 5-minute timeout of their own: the SDK's 30s default was cutting off federated joins (seen joining a matrix.org space from m.uwu.lt) that the server then finished anyway. The join is sent by hand with that timeout, then join_room_by_id_or_alias runs again, which returns instantly now that we're in and does the SDK's local bookkeeping. resolve_room became unused and is removed.
• Error messages now include their source chain, so transport failures say why (e.g. "operation timed out") instead of a bare "error sending request for url".
• Space-wide settings are per room underneath. Matrix has no space-level push rule, so mute and notification level apply to every joined room in the space, and the menu reads the current state back from those rooms ("mixed" when they differ). RoomSummary gains notifyMode. New bulk commands set_rooms_notify_mode and mark_rooms_read run room by room, because concurrent push-rule writes race on the SDK's cached ruleset.
• Mark read without opening a room sends a receipt on the room list's latest event and clears the manual unread flag.
• Hide muted rooms is a local setting per space (hideMutedInSpaces), and only affects that space's list.
• New shared ContextMenu (separators, checkboxes, radios, flyout submenus) and isInSpace / roomsInSpace store helpers. filterRooms uses them.

Testing

• tsc -b clean; vitest 178 passed (new: src/store/spaces.test.ts); cargo test 122 passed; no new clippy warnings
• Exercised in a stubbed browser harness: directory search, paging, server error, join, browse rooms, every menu action, phone-width layout
• Not yet verified: against a real homeserver (federated directory reads, via joins, the longer timeout), or long-press on an actual phone
