wtclaude baffaa46c9 feat(rust): identity — a link code from the game, and the Steam id inside core's user page
R1's identity link, site-side, and R13's first extension slot. A player types
/link in game, the plugin hands them a six-character code privately, and they
enter it here; the site records who owns which Steam account, and an operator
sees that on core's own `/admin/users/:id` page.

**The site is the author of record and the game holds nothing.** There is no
per-account store in Rust that survives a wipe, and phase 7 needs the site
authoritative anyway — it pushes permissions INTO the game keyed by Steam id. A
copy in the game would be a second thing to reconcile every wipe, for no question
it could answer better.

## D24 — a code is minted by ONE server, so every server is asked

Nothing in six characters says where it came from. The fleet is asked in turn and
the first `link.ok` wins; the others answer `unknown` and nothing happens there,
because a code is only spent at the server that actually holds it. Asking the
player to pick was rejected: a wrong pick would come back indistinguishable from
a wrong code, and that is the one refusal which must not be ambiguous.

**"Every reachable server refused" is not the same answer as "a server was
unreachable."** Collapsing them tells a player whose server is down that their
code is wrong — so they run /link again on that same server and are told the same
thing for as long as it stays down. `unsure` is that case, and it says to try
again rather than to fetch a new code.

## D23 — a Steam id another account holds is refused, never moved

The primary key is `steam_id`, and it is load-bearing rather than tidy: phase 7
grants permissions against a link and phase 13 hangs entitlements off it, so a
silent move is an account takeover performed by typing six characters. The
refusal names the holder, because the advice is unusable without it. The INSERT
is a plain INSERT for the same reason — `ON DUPLICATE KEY UPDATE` here would BE
that move — and the duplicate-key error is the refusal for the race the check
above cannot close.

The way out is `/unlink` in game, which reaches the site off the ingest feed
rather than through a route (the plugin has no link to delete). D25 adds the
other way out: staff can sever a link from the admin panel, for a player who
cannot reach that Steam account in game.

## The slot, and the hole it found in this repo's own generator

`admin.users.detail` is declared in `module.json` AND registered in `index.js`
AND filled by the chunk — three places, because the server half and the client
half are different registrations that share one name.

`swaggerFragment.js` knew only about tier routers, so the two routes under
`/admin/users/:id` were generated by nothing: a fragment that was internally
consistent and described two routes fewer than the module serves. A slot's mount
is core's and cannot be derived here, so it is a fourth constant beside
`TIER_BASE` — held to account by the frozen-manifest job, which was verified to
catch exactly this by removing the two paths and watching it fail.

## Smaller things worth knowing

- **Core's `useAsync` has no `refresh`.** A counter in the deps is how a page
  re-reads after its own write; it blanks while it re-reads, which is right here
  and is exactly what made it wrong for a poll.
- **Every player-portal nav row needs an `icon`** — core draws one on every row,
  and the client suite says so. This module had no icons file until now, because
  the public header is text buttons.
- The two new frame kinds are STAFF-only. Neither carries a code, but both name a
  Steam id beside a website account's activity, and that join is not a public
  fact about what happened on a server.
- The link code route carries its own rate limiter rather than core's
  `accountChangeLimiter`: this is guessing somebody else's secret, not changing
  your own password, and a shared counter would let one policy set the other.

Protocol 3 on all three declaration sites; 17 new tests, 136 green.

// ── The `admin.users.detail` extension slot ───────────────────────────────
//
// R13's first slot, and the phase criterion in one file: *an operator sees the
// Steam id inside core's own user page*.
//
// MODULE_API.md §2.4's fourth mount shape — module routes hanging off a CORE
// resource. `/admin/users/:id` is a URL core owns and this module has something
// to say about it, so the routes cannot move behind a `/rust` prefix and cannot
// be registered anywhere else either. Core declares the slot; a module fills it,
// and only one module may.
//
// Three things about this router that are not true of the other three:
//
// • **`mergeParams: true`**, because the user id belongs to the parent. Without
// it `req.params.id` is undefined and every statement here silently scopes to
// nothing.
// • **The paths keep the module's own segment** (`/rust/links`, not `/links`).
// Core owns the resource and other modules may fill their own slots on other
// resources; a bare `/links` would be this module claiming a word on a URL it
// does not own.
// • **The gate is stricter than the admin tier's.** Core's users router is
// `requireRole('admin')` and the slot is mounted inside it, so editors and
// moderators never reach here — which is right for a surface that can sever
// what phases 7 and 13 grant against.
//
// The client half is registered under the SAME name (`registry.registerExtension`
// in `entry.jsx`) and builds its own client for these two routes; a slot passes a
// component `userId` and nothing else.
