fix(rust): protocol 13 step 2 — expiry, plugin loads, the loading hold, NPC names, the link fleet (F2 F5 F6 F7 F8 F13 F14)

The module's half of PLAN_FIXES §6 step 2 (decisions D181-D185, docs#288).

- F13/F14 (D170, D183): `world.expired`, recognisable from protocol 13 by its
  `what`, is handed to core as the resource the zone step ledgered
  (`world`, `<serverId>:<id>`) through ctx.events.expired, which records it
  `expired`. coreApi moves to ^1.11.0 (website#209).
- F8 (D184): `plugin.loaded` / `plugin.unloaded` mark the permission sync dirty
  when the plugin added or removed permissions, so an unresolved grant lands on
  the next tick instead of the fifteen-minute audit.
- Catalogue: plugin.loaded/unloaded, world.expired and lease.expired are staff
  kinds. The last two were never classified (default deny kept them off public
  pages); the test now covers every event kind through protocol 13.
- F7: permission and title pushes hold while the stored hello says
  `worldReady: false` (a human's "sync now" does not); a failed or refused
  permission sync now logs at warn.
- F2 (D185): the killfeed names an NPC attacker — a family (Scientist, Bandit
  guard, Bradley APC…) or the prefab without its variant digits (wolf2 → Wolf).
- F5/F6: a link code is asked of the servers that minted one in the last six
  minutes first, then of the rest, each group in parallel; "unsure" only when
  one of the minting servers is unreachable.
- D182: the admin server list carries the ZoneManager helper's state from the
  hello, and the servers page says what a missing or failed helper costs.
