feat(bridge): Rust's own world events on protocol 14 (PLAN_REDESIGNS §14.3.1)

Stage 1 of the §14.3 integration plan: the patrol helicopter, Bradley, the
cargo ship, the Chinook, airdrops, locked crates, the Travelling Vendor, the
satellite and the Deep Sea, with no plugin (D349).

- `world.event`, one frame kind whose `event` names which of 24 types
  (PROTOCOL.md §20.5). The type is in `event`, never `type`: `type` is the
  envelope's, and the rig's sidecar dropped every world event as untyped when
  the plan's example put it there. Nothing is said before the world loads or
  while the server quits. Positions are x/z; the site works out the grid.
- Credit (D372, D379): a damage table for the patrol helicopter, the Chinook
  and Bradley; `heli.downed`, `chinook.downed` and `bradley.destroyed` carry
  every candidate (blow, last, most, damagers) and the plugin credits nobody.
  D174's `CreditVehicle` and the tally's apcKills/heliKills are gone.
- Locked crates told positively (oil rigs, cargo, ghost ship, a Chinook drop
  joined at the crate's landing); anything else says nothing. A Bradley's
  `where` comes from the game's spawners, not `RoadSpawned` (which defaults to
  true). `airdrop.called` comes from the cargo plane's spawn: `supply.call`
  raised neither OnAirdrop nor OnCargoPlaneSignaled.
- The tally gains cratesHacked and dropsLooted (Safecracker, Scavenger, D356).
- `world.call` (D354, D367, D378): one of a schedule's TriggeredEvents at
  random, without Trigger (which would reset its clock); satellite.random for
  the satellite. A position for the airdrop (InitDropPosition) and the patrol
  helicopter (SetInitialDestination) only, both set before the spawn, as the
  stage-1 spike measured (0-1 m and 10-54 m). Kept; the key is remembered seven
  days in world-calls.json; EventsMaxWorldCalls (default and ceiling 10) per run.
- Hello/status `console.plugins` (D363): the bridge runs its own rg.probe
  through ConsoleSystem.Run from a timer. Carbon 2.0.262 refuses plugin
  commands only inside a console command (or a NextTick one queued), which is
  how §14.2's spike tested; from a timer, and from the link reader's NextTick,
  it finds them. Reads true on both rigs.
- checkPlugin.js: the probe must name a [ConsoleCommand] the plugin declares.

Compiled and loaded on both rigs (Rust 25902425, Oxide 2.0.7830, Carbon
2.0.262); heli.arrived, cargo.arrived and airdrop.called read back from each
rig's sidecar store. Rigs restored. 18 check tests pass.

+Rust's own world events need no plugin at all. The patrol helicopter, Bradley, the cargo ship, the
+Chinook, airdrops, locked crates, the Travelling Vendor, the satellite and the Deep Sea reach the
+site's feed and its event triggers on every server, and an event can call one of them (`world.call`).
+What a call starts is kept when the event ends; `EventsMaxWorldCalls` caps how many one run may call.
