feat(events): the integrations — lifecycle triggers, participants, results (Phase 10)

`EVENTS_PLAN.md` Phase 10. Core registers its own `event.` triggers, records who
took part, publishes a results table, and announces a post through the legs the
news pipeline already uses. Events owns none of the delivery: a run says what
happened and an operator's rule decides who is told, so email, the in-app inbox,
push tickles, Discord and the town crier all arrive without anything in
`events/` growing a second delivery path.

**No route was added and nothing moved.** The whole surface is two more derived
fields on a run — `participants` and `resultsPublishedAt` — and a zero-line
`routes.manifest.json` diff proves it.

Seven triggers: six at ceiling `authenticated` / audience `subscribers`, exactly
where `news.post` sits, and `run.failed` at `admin` on both halves. Every one
keys its cooldown on the RUN. Two rules seeded, both off, under a third one-shot
key so a deployment that has already stamped the Team and news keys still gets
them.

**The phase's own defect was a promise nothing kept.** `EVENTS.md` §I says a
rehearsal runs for real "with announcements ceilinged to `staff`" — but a
ceiling is declared on the TRIGGER, and a rehearsal fires the same trigger as
the real thing, so the moment this phase gave a run something to announce,
rehearsing a published event would have mailed every subscriber. The emit
envelope now takes an optional `ceiling` and the send-time G24 gate applies
`meet(declared, emitted)`. It only narrows; two incomparable ceilings refuse
every rule rather than resolving to either.

`MODULE_API_VERSION` stays 1.10.0, amended in place — `main` declares 1.9.0, so
1.10.0 has not shipped and the org lead's 2026-09-03 rule applies for the third
time.

Three defects the live walk found, none visible to a unit test:

1. **A channel that reported success while reaching nobody.** The seeded
   `run.started` rule named `push`, because §8.5 and the plan both do. Push
   delivery joins `notification_subscriptions`, only ever written for an id the
   preferences screen offered push for — and it offers push only for a
   registered STREAM. So the tickle went nowhere every time while
   `pushChannel.deliver` answered "tickle published". `event.run.started` is now
   a stream as well as a trigger; the other six are not.
2. **A trigger's `description` reaches a recipient.** It is the structural
   projection's `intro` fallback, so `run.failed`'s line ending "Staff-facing."
   put those words in an administrator's own inbox item.
3. **`affectedRows` cannot tell an insert from an unchanged upsert.** The
   connector sends `CLIENT_FOUND_ROWS`, so a "was this new" flag would have
   counted every idempotent retried collect as a fresh participant.

And one caught before it shipped: ranking with a session variable is wrong here,
because `query()` takes a pool connection per call — the variable would be set
on one connection and read on another. A window function needs no session state.

## Verification

- `npm test --prefix server` — **1981 pass, 1 fail**, and that one
  (`botScore.test.js`) passes standalone at 18/18: a file-level flake under
  parallel load. Run with an empty `MODULES_DIR`, as CI does.
- `npm test --prefix client` — 362 pass, 0 fail. `npm run build` green.
- Zero-line `routes.manifest.json` / `routes.guards.json` diff.
- A live walk on a real rig: MariaDB, the site with no module, mailpit. The mail
  arrived, headed with the event's title and its start time in the shard's own
  zone; the rehearsal fired the same trigger and produced zero outbox rows where
  the real run produced three; `run.failed` reached the administrator's inbox
  and no player's; `core.announce.post` queued a second job without touching the
  news pipeline's back-pointer or `announced_at`; and `rankRun` and the upsert
  were run against real MariaDB 11.

## One thing for a reviewer, out of scope and not fixed

**Every `#swagger.description` in this repo is truncated in the generated spec.**
swagger-autogen does not honour a backslash-escaped apostrophe, so a description
is cut at the first `\'` — 175 of the 177 in `server/src/router/**`. It is
pre-existing and repo-wide. Only the one annotation this phase edits is fixed
here (a typographic apostrophe), because otherwise this phase's own addition to
it would be dead text. The rest wants its own change.

+  // ── The event system (EVENTS.md §J — Phase 10) ──────────────────────────
+  //
+  // **Seven triggers, one per moment a run passes through that somebody outside
+  // the run console might want to hear about — and Events owns none of the
+  // delivery.** A run emits; an operator's rule decides who is told, on what,
+  // and how often. That is the whole of §J's "clean fit" row, and it is why
+  // there is no announcement machinery anywhere in `utils/eventRunner.js`
+  // beyond a call to `emit`.
+  //
+  // **Six are ceilinged `authenticated` and one at `admin`** (§J, and the org
+  // lead 2026-09-04). `run.failed` is an operational fact — a step ran out of
+  // attempts, the world may be half-changed — and a rule that mailed it to
+  // every subscriber would publish the deployment's incidents. The other six
+  // describe a public event happening in public, so they sit exactly where
+  // `news.post` sits: ceiling `authenticated`, default audience `subscribers`,
+  // which is "people who asked to be told" rather than the whole user table.
+  //
+  // **Every `description` here is read by two audiences**, and the second one is
+  // easy to forget: the rule editor's catalog, and — through
+  // `projection.project`'s `intro` fallback — every recipient of an unauthored
+  // render through `notify.event` or `inapp.event`. So each is prose a player
+  // can read rather than a note to the operator. The live rig caught the
+  // original `run.failed` line, which ended "Staff-facing." and put those words
+  // in an administrator's own inbox item. Who a trigger is for is said by its
+  // CEILING, which is the only place that can enforce it anyway.
+  //
+  // **`subjectKey: 'runId'` on every one of them**, and it is the one place
+  // these differ from `news.post`. A cooldown keyed on the user would make
+  // `phase.changed` mean "at most one phase of at most one event an hour",
+  // silently swallowing the second wave of an invasion because the first wave's
+  // mail went out forty minutes ago. Keyed on the run it means "at most one
+  // line an hour ABOUT THIS RUN", which is the useful sentence — and across
+  // runs of the same definition the ids differ, so a weekly event is not
+  // throttled by last week's.
+  //
+  // **None of the six public ones declares a `url` variable, deliberately.**
+  // There is no public event page until Phase 14 — `App.jsx` mounts nothing
+  // under `/site/events` — and `news.post` has already paid for this mistake
+  // once: its `postUrl` example named `/news/<slug>`, a path that does not
+  // exist, and the template editor previewed a link that was dead in every mail
+  // it sent. A variable added in Phase 14 alongside the page it points at is a
+  // version bump; a variable shipped now is a 404 in an operator's first
+  // announcement. `run.failed` is the exception because its destination exists
+  // today: `/admin/events/runs/:runId` is a real route and an admin can read it.
