docs(account): fix stale transitional wiring NOTE in index.ts

[os-warren]

Fixes#9696

What

packages/apps/account/src/index.ts carried a transitional header NOTE claiming
the package was "NOT yet wired into the dev/serve plugin set." That boot-path
switch has already landed — this PR rewrites the stale half of the NOTE to
match reality, comment-only.

Evidence

• packages/cli/src/commands/serve.ts:2293-2295 loads @objectstack/account
  in the ADR-0048 platform-app loop:

  for(const[appPkg,factory]of[['@objectstack/setup','createSetupAppPlugin'],['@objectstack/account','createAccountAppPlugin'],]asconst){

• The boot path has been verified against a live os dev boot: a
  @objectstack/cli@17.0.0 boot on a clean home lists @objectstack/account
  among the 30 loaded plugins — measured transcript in
  quickstart.mdx sample os start output does not match what CLI 17.0.0 prints, and the plugin count is wrong objectos#94, comment 5329804967.
• The other half of the NOTE — ACCOUNT_APP is still imported from
  @objectstack/platform-objects/apps — is still true and is kept verbatim.

Scope

Comment-only diff, one file, no executable line changed:

 * NOTE (transitional): `ACCOUNT_APP` is still imported from
-* `@objectstack/platform-objects/apps`, and this package is NOT yet wired into
-* the dev/serve plugin set — that boot-path switch lands separately so it can
-* be verified against a live `os dev` boot.
+* `@objectstack/platform-objects/apps`. The package IS wired into the
+* dev/serve plugin set — `packages/cli/src/commands/serve.ts` loads it via
+* the ADR-0048 platform-app loop (`['@objectstack/account',
+* 'createAccountAppPlugin']`) — and that boot path has been verified against
+* a live `os dev` boot (transcript: objectstack-ai/objectos#94, comment
+* 5329804967).

Changeset

Comment-only change in a published package — no user-visible behavior change.
Rationale for skip-changeset label (this repo's real mechanism; see PR #9918,
PR #10017 for worked examples), applied to this PR rather than an empty
changeset file.

Tests

• pnpm --filter @objectstack/account typecheck — pass, unchanged from main
  (comment-only diff).
• pnpm --filter @objectstack/account test — package has no test script
  (build, typecheck only); nothing to run.
• Named gates re-derived via node scripts/pm/dispatch-gates.mjs against the
  actual diff (4 matched: check:slot-lookup, check:test-source-alias,
  check:type-source-resolution, check-affected-docs.mjs) — all pass, see
  dev report for verdict lines.
• Ablation: not applicable — nothing executable changed.

📓 Docs Drift Check

1 anchor(s) derived from 1 changed package(s); no hand-written page names any of them. ✅

What this run could not see

Coarse fallback — 1 page(s) merely mention a changed package (the pre-#9192 predicate, kept for the deliberately-wide backstop): node scripts/docs-audit/affected-docs.mjs --json 43cd348a2f0b91ea1035c4c055fbed160bfb4aca → packageMentionDocs.

Which tree this was computed on

This run read content/docs from 436a08e075551d385c30d9f9bb9077426a079552 — the merge of head 2705d5f8a66932a35abdcfe1f48ae44e112ffda4 into base 43cd348a2f0b91ea1035c4c055fbed160bfb4aca, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

# while this PR is open — GitHub drops the merge commit once it closes
git fetch origin 436a08e075551d385c30d9f9bb9077426a079552 && git checkout 436a08e075551d385c30d9f9bb9077426a079552
# afterwards, rebuild it from the two parents, which stay fetchable
git fetch origin 43cd348a2f0b91ea1035c4c055fbed160bfb4aca 2705d5f8a66932a35abdcfe1f48ae44e112ffda4 && git checkout -B drift-repro 43cd348a2f0b91ea1035c4c055fbed160bfb4aca && git merge --no-ff 2705d5f8a66932a35abdcfe1f48ae44e112ffda4

⚠️ That checkout carried uncommitted changes, so the commit above does not fully identify what was read.
