fix(create-objectstack): exclude CHANGELOG.md from the skills-catalog-boundary ratchet (unblocks main Test Core)

[os-zhuang]

Problem — Test Core is red on main

The required Test Core gate has been failing on main since before the current head (first seen at e412fb676 / 631debac5; last green 629fbae80). One test fails:

create-objectstack › template-consistency.test.ts › skills catalog boundary › no customer-facing surface advertises a repo-root skills install

Root cause

The guard greps content/docs / skills / packages/create-objectstack for skills add objectstack-ai/framework not followed by /skills, excluding only the test file — not CHANGELOG.md.

When Changesets versioned create-objectstack in RC mode, it baked #3101's changeset prose into packages/create-objectstack/CHANGELOG.md:99. That entry documents the fix by quoting the removed command in past tense:

"…the scaffolder (and the docs) advertised npx skills add objectstack-ai/framework --all … All install commands are now scoped to the published catalog via the /skills subpath…"

The ratchet flagged that historical quote as a live advertisement. Every real advertising surface (content/docs/**, README.md, src/index.ts, templates/AGENTS.md) already uses the correct /skills subpath — the CHANGELOG is the only "offender", and it's a false positive.

Fix

Exclude **/CHANGELOG.md from the guard's grep surfaces. A changelog documenting the removal of an anti-pattern is not advertising it. One line + rationale comment.

Verification

pnpm --filter create-objectstack test → 18/18 pass (was 1 failing). Reproduced the single offender locally and confirmed the :(exclude)**/CHANGELOG.md pathspec drops it (1 → 0 matches).

Notes

• Pre-existing failure, unrelated to discovery 广播「跨对象原子 batch」能力位(让客户端声明式协商,取代 404/405/501 运行时探测) #3298/feat(discovery): broadcast transactionalBatch capability bit so clients negotiate atomic batch declaratively (#3298) #3345 (discovery capability) — that PR's own Test Core was green pre-merge; its post-merge run was cancelled (superseded by feat(approvals): server-computed viewer capability for precise decision-action gating (#3310) #3344), not failed.
• skip-changeset: test-infra only, nothing shipped in the published package.
