Fixes #25666

Clause-②: no
Metadata-protocol: none

## 维护者速读(草稿)

- **改了什么**:已发布技能 `objectstack-platform` 的 bootstrap 示例里,五个
`@objectstack/*` 依赖还写着 `^17.0.0`。改成和脚手架一样的精确版本 `18.1.0`。原计划加的一句说明被已发布技能的
token 上限挡住(只降不升),已删去,精确版本本身已表达同一意思。
- **为什么改**:PR #25539 起脚手架写精确版本,v18 文档也要求锁精确版本;照技能抄的人会装到 17.x,还是 caret
范围。
- **风险与代价(含回滚)**:纯文档,附一条 `@objectstack/skills` patch changeset;一次 revert
可回。
- **你要做的(一个动作)**:`skills/**` 属 Tier H,复核通过、CI 全绿后请您合并。

## What changed

- `skills/objectstack-platform/references/bootstrap.md` 〈Complete
Working Example〉 `package.json`: `@objectstack/spec`, `runtime`,
`driver-memory`, `plugin-hono-server`, `cli` go from `^17.0.0` to
`18.1.0`; `typescript` keeps `^5.3.0`. No prose added: a first commit
added one sentence (the scaffolder writes its own version, exactly), and
the published skills token ratchet
(`scripts/check-skills-token-ratchet.mjs`, #10473) refused it, 1391
tokens against a shrink-only ceiling of 1351; the second commit drops it
(1350 / 1351) rather than ask for a ceiling ruling.
- `.changeset/25666-skills-bootstrap-exact-pins.md`:
`@objectstack/skills` patch.

Grounds: `packages/create-objectstack/src/pkg-utils.ts`
`syncObjectStackDeps` (`deps[dep] = version`, PR #25539);
`content/docs/protocol/backward-compatibility.mdx` L206 and
`content/docs/deployment/self-hosting.mdx` L64 (pin exact);
`packages/create-objectstack/package.json` `18.1.0`.

## Gates

On this head: `node scripts/check-skills-token-ratchet.mjs` ✓
(bootstrap.md 1350 / 1351), `pnpm check:skill-frame-sync` ✓, `pnpm
check:skill-frame-freshness` ✓, `pnpm check:skill-identifier-liveness`
✓, `pnpm check:skill-compatibility` ✓,
`scripts/check-empty-changeset.mjs` ✓,
`scripts/check-commit-card-trailers.mjs --range origin/main..HEAD` ✓.
`git grep -n '"\^1[0-9]\.' skills/` finds nothing (it found these five
lines before).

## Acceptance notes

- Not in scope: `engines: { protocol: '^17' }` in
`objectstack-platform/SKILL.md` L142 is the protocol handshake range, a
different value. The template baseline and its release-time stamping are
PR #25665 (`domain:devx`).
- The literal `18.1.0` will age with each release like any versioned
example.
- Governed surface `skills/**` (Tier H): lands by the maintainer's hand.
Opened through the fleet-write relay `pr_create`; every later write goes
through the relay too.

+The 〈Complete Working Example〉 `package.json` in `objectstack-platform/references/bootstrap.md` gave `^17.0.0` for its five `@objectstack/*` packages, a major behind and a caret range the v18 docs advise against. It now gives `18.1.0` for each, the exact form `create-objectstack` writes, with all of them on one version.
