docs(rust): the last fixes' docs (N1 N2 W20 W22 W23) and stage 4's core docs

Stage 5 of PLAN_LAST_FIXES (docs#366).

- OPERATING.md: a RaidableBases section. Change its config with a
  restart, never a reload (N2); switching to the free edition rewrites
  a paid pack's profiles (N1).
- PLAN_REDESIGNS 14.3.4: no manual retry for Dangerous Treasures (Q39,
  W20); 11.4: which hook rbevent setowner raises (W23); 9.1 status.
- PLAYER_WALK: rows 2.2, 2.8 and 2.9, Before you start item 8 (BetterChat
  and the four title rules), Carbon's share trimmed to 2.11 (W22, W23).
- PROTOCOL: 20.5 world.error already-out (W3), 20.12 the rollback's log
  is RaidableBases' own (W9) and setowner's two hooks (W23).
- Core, from website#219: MODULE_SYSTEM 2.5 and MODULE_API 4.2 (one
  module at boot, W19), MODULE_API and EVENTS L (a resource's until read
  at reconcile, W1), EVENTS D/I/K and BACKEND_DESIGN (a draft's dry run
  carried by fingerprint, W5), EVENTS observability (W2's words).
- PLAN_LAST_FIXES: status, Q37-Q40 answers, 7 updated, 8 what was built.

+<sub>Runic Gateway's own section, not mirrored. Design: [PLAN_REDESIGNS.md](PLAN_REDESIGNS.md) §11.4; wire:

+
+**RaidableBases** is one of the optional plugins Runic Gateway reports and drives, in either edition (D348).
+Two of its own behaviours catch operators out.
+
+**Change its config with a server restart, never a reload (N2).** *Applying changes* above says to reload a
+plugin after editing its config. Do not do that with RaidableBases while the server is running. After
+`oxide.reload RaidableBases`, its list of live raids can hold an empty entry. Every hook that walks that list
+then fails: damage to a base, its SAM sites, players' commands, and `/buyraid`'s cooldown check, so a purchase
+does nothing and charges nothing. The end walk saw this after reloads with and without bases up, and only a
+full server restart cleared it. It is RaidableBases' own bug. Carbon's `c.reload` was not tried in the end walk, so treat it
+the same way: edit the config, then restart the server.
+
+**Switching from the paid edition to the free one rewrites the paid profiles (N1).** Putting the free
+edition's `RaidableBases.cs` in place of the paid one rewrites the profiles a paid base pack installed, and
+their bases are dropped from them. Going back to the paid edition does not bring them back. Back up
+RaidableBases' config and data folders before you switch editions, and restore them if you switch back.
