docs(rust): stage 4 built — Dynamic PVP's zones (PROTOCOL §20.7, PLAN_REDESIGNS §14.3.17)

- rust-link/PROTOCOL.md §20.7: hello's integrations.dynamicPvp, the two
  events and their fields, the sphere/cube shape and the live position, the
  quiet while the world is not live, map.live's pvp layer and its seed from
  Dynamic PVP's own API, and the website's classes, per-viewer reading and
  fifth map layer. §17.3's table gains the pvp row.
- modules/rust/PLAN_REDESIGNS.md §14.3.17: the stage-4 record — three things
  §14.3.3 had wrong or unsaid (the seed, cube zones, cargo's moving zone),
  eight points settled in code (all overrulable), the tests and the rig
  compile. Pointers from §9's summary and §14.3.3.

+### 20.7 Dynamic PVP's zones — `pvp.zone.created`, `pvp.zone.deleted`, the `pvp` layer (§14.3.3)
+
+HunterZ's **Dynamic PVP** (5.2.0, uMod; it requires ZoneManager and TruePVE), optional like Economics (D199)
+and not in `overlay.toml`. It opens its own PvP zones around a downed patrol helicopter, a Bradley, a locked
+crate, an airdrop, the cargo ship and the rest. **The bridge only reports them**: it never makes, maps or
+erases a Dynamic PVP zone, and nothing on the site starts one. The design is
+[`PLAN_REDESIGNS.md`](../modules/rust/PLAN_REDESIGNS.md) §14.3.3; what the §14.2 test found is §14.2.1 there,
+and what the build found in Dynamic PVP's own source is §14.3.17.
+
+**Hello and status.** `integrations` gains `dynamicPvp`:
+
+```json
+"dynamicPvp": { "loaded": true, "version": "5.2.0" }
+```
+
+Hello is sent again when Dynamic PVP loads or unloads. `rg.world` prints `dynamicPvp=` and `pvpZones=` (the
+zones the bridge knows are live).
+
+**Two events**, from Dynamic PVP's own hooks:
+
+```json
+{"kind":"pvp.zone.created","type":"event","zoneId":"1412203045","event":"Helicopter",
+ "x":812.4,"z":-340.5,"radius":100,"shape":"sphere","durationSec":600}
+{"kind":"pvp.zone.deleted","type":"event","zoneId":"1412203045","event":"Helicopter"}
+```
+
+- **`pvp.zone.created`** is `OnCreatedDynamicPVP(zoneId, eventName, position, duration)`. `event` is Dynamic
+  PVP's own name for what opened it: one of its vanilla events (`Bradley`, `Helicopter`, `Satellite`,
+  `TimedSupply`, `SupplySignal`, `CargoShip`, `HackableCrate`, `ExcavatorIgnition`, `GhostShip`,
+  `DeepSeaIsland`, `IslandCannon`), a monument's name for a monument zone, or an operator's own event name.
+  The hook carries no size, so **`radius` and `shape` are read from ZoneManager**: a sphere's `Radius`, or for
+  a cube (cargo's) half the longer of its `Size` across the ground, `shape: "cube"`. **`x`, `z` are where the
+  zone is**, from its transform, which for a parented zone (cargo) is the ship. `durationSec` is −1 for a zone
+  that lasts as long as its event (cargo, a monument's).
+- **`pvp.zone.deleted`** is `OnDeletedDynamicPVP(zoneId, eventName)`, for a zone the bridge knew.
+- **Neither is sent while the world is not live** (§20.5's rule): a boot or a shutdown opens or closes every
+  monument zone at once, and that is not news. Dynamic PVP's own unload deletes every zone and is said, as
+  `deleted` lines.
+- Dynamic PVP's ids are numeric (a time stamp, or the entity's net id), never one of the bridge's `rg-…`.
+- `OnPlayerEnterPVP` / `OnPlayerExitPVP` are not subscribed: they would say who stands where.
+
+**The `pvp` layer of `map.live`** (§17.3) is every zone the bridge knows is live and ZoneManager still holds,
+with where it is **now** (cargo's moves with the ship), `radius` and `shape`. The bridge keeps the set by the
+two hooks, and **seeds it from Dynamic PVP itself** (`AllDynamicPVPZones()`, `GetEventName(zoneId)`) when the
+world is ready and when Dynamic PVP loads, because a hotload of the bridge hears no creates. A zone ZoneManager
+no longer holds is dropped from the set when the layer is read.
+
+**Hooks.** `OnCreatedDynamicPVP` and `OnDeletedDynamicPVP` join `rg.hooks`' list.
+
+**The sidecar** stores and forwards the two frames like every other event, and `map.live` whole; nothing in
+it changed.
+
+**The website (Module-Rust).**
+
+- **`pvp.zone.created` is a public kind, `pvp.zone.deleted` a staff kind.** Each row is read per viewer by
+  `dynamicPvp.shapeFor`, as a world event is (§20.5): everyone gets `grid`, `radius`, `shape` and
+  `durationSec`; **`event` only when it is one of Dynamic PVP's vanilla events**, because a monument's or an
+  operator's name is the operator's own text; and **`x`, `z`, `zoneId` only for staff**, because the map has its
+  own audience for where things are (D111). The public line reads *"A PvP zone opened around the downed patrol
+  helicopter · G7 · for 10 min"* and names nobody. No trigger and no step.
+- **The map gains a fifth layer, `pvp`** (*PvP zones*), with its own audience in Admin → Rust visibility
+  (`map.layer.pvp.audience`), **public by default**: the game shows the zones to everybody near one, and they
+  name nobody. It is drawn as a red ring with its event's name.
+- Server settings' plugin line says whether Dynamic PVP is loaded.
