fix(kit): everything the acceptance run found — Phase 5 slice 3

A cold agent was given this repo and the documents it links to, and nothing
else — no core source, no module-uo — and asked to build a module for a second
game. It did, in one pass. The record is docs/modules/kit-acceptance.md; this is
the repair list, plus the two things it recommended that were not defects.

The one it could not find, because it had no core to render against: a module
page built exactly as this kit teaches renders OUTSIDE the site. PublicLayout is
the chrome, not the body. Core grew an opt-in `shell` prop for it
(MODULE_API_VERSION 1.5.0, website#148); the template passes shell="narrow" and
chapter 2 explains why you name a width and never a class.

Fixed:

- **F1, and the worst of them, because it lands in the first twenty minutes.**
  `npm run check:swagger` failed on a PRISTINE template on Windows: the check
  compared the committed fragment byte-for-byte and a default Windows clone is
  CRLF while the generator writes LF. The message blamed "the routes or their
  annotations". Now `template/.gitattributes` pins `eol=lf` and the comparison
  normalises line endings anyway — a check may only fail for the reason it names,
  and this one names a diagnosis.
- **F3** — `.gitea/workflows/release.yml` carries `gitea.example.com` and
  `your-org/your-module` under a literal `# CHANGE THESE`, was not in the rename
  checklist, and `checkRenameSites.js` could not match it, so CI was silent by
  construction. Row added, pattern widened. (The agent reported both workflow
  flavours; only the Gitea one is affected — GitHub supplies its own variables.
  Corrected in the record.) The near-miss is kept in the check's comments and its
  suite: the obvious widening is `example\.com`, which fires on a fixture URL in
  checkImports.test.js. Every alternative has to be a string that cannot occur by
  accident, which is the same rule that made the id `examplegame`.
- **F4** — the release bundle's include list was hardcoded, so adding
  `server/utils/` would have silently dropped it from every release while the
  bundle check stayed green. Inverted to an exclusion list, in both flavours, and
  run by hand because a release workflow never executes in CI.
- **F5** — the annotation-quoting warning was wrong in both directions, and the
  correction is measured rather than reasoned. A backtick is harmless (the
  template's own description has two spans and they survive). A `"` is not, and
  it does not throw: `'A "quoted" status'` is silently TRUNCATED to `A "` while
  swagger-autogen prints Success and the error capture sees nothing. The only
  signal is check:swagger blaming your routes.
- **F6** — `template/.gitignore`, so a copied template that is `git init`ed
  inherits ignore rules instead of nothing.
- **F7** — the UI kit is eight exports across five rows, not seven. The contract
  said seven and this kit had faithfully carried the miscount out of it.

Adopted, not defects:

- Chapter 1 now says to run every check on the untouched copy first. That is what
  found F1; without a baseline the first failure is ambiguous forever.
- The template ships the §2.7 self-check the agent wrote for itself. The rule has
  no CI in general — an outbound socket is not statically detectable — but a
  module can make a decidable claim about its own tree. Ported from its code with
  a header explaining how to NARROW it when a sidecar client arrives, since
  talking to your sidecar is the expected shape and is not what §2.7 forbids.

The pin moves to website edge 4ad8b2b, the 1.5.0 bump, and template/module.json
declares ^1.5.0 — so checkCoreApi's equality assertion still holds and the
template uses a member that exists only at that ref and later.

32 server + 18 client template tests, 21 kit-script tests, all four checks green.

+// ── §2.7's last rule, given the CI it does not have ───────────────────────
+//
+// `book/02-website-module.md` is explicit that "the website process never opens a
+// connection to a game server" is the **one boundary rule with no CI behind it**:
+// an outbound socket is not statically detectable the way an internal `require`
+// is, so in general the rule is held up by review and by understanding it.
+//
+// True of the general case, and not a reason to check nothing. A module can state
+// a narrower, completely decidable property about **itself**, and this one says:
+// the shipped server half references no networking primitive at all. Everything
+// it knows arrives from its own tables, which its sidecar writes.
+//
+// Adopted from the kit's acceptance run (`docs/modules/kit-acceptance.md`), where
+// a reader building a Rust module wrote it unprompted after reading that the rule
+// had no CI — and observed that for Rust in particular, which ships RCON over
+// WebSocket, `new WebSocket(rconUrl)` in `boot.js` is about ten lines away.
+//
+// ── WHEN YOU ADD A SIDECAR CLIENT, NARROW THIS. DO NOT DELETE IT. ─────────
+//
+// Talking to *your sidecar* over HTTP is the expected shape and is not what §2.7
+// forbids — the rule is about the **game server**. So the moment your module
+// grows, say, `server/sidecarClient.js`, this test starts failing correctly and
+// the fix is to allow that one file:
+//
+//     const MAY_OPEN_SOCKETS = new Set(['sidecarClient.js'])
+//
+// and keep the rest of the tree under the ban. What you get for that is a test
+// that names the *one* file allowed to reach the network — which is exactly the
+// file a reviewer should be reading closely, and exactly the place a game-server
+// URL would appear if the rule were ever broken.
+//
+// Scope: SHIPPED code only. `test/` and `scripts/` never run inside core's process.
