test: remove stale README copy checks from showcase catalog smoke

[huangruiteng]

The README positioning and preset heading changed on main, but showcase-catalog-smoke.py still required the old text. That made the showcase check fail on an otherwise valid checkout and blocked unrelated PR CI. Remove those three presentation-copy assertions from the catalog smoke. The separate README entry smoke already checks the current README structure and recurring-work heading; the catalog smoke continues to verify showcase links and case coverage.

Validation: showcase-catalog-smoke.py and readme-demo-surface-smoke.py pass; changed-file public scan and git diff --check pass. Goal-scoped quick premerge passed all 8 selected/direct checks with no failures or manual holds. Exact-scope change-quality receipt: cqr_e10aec7a6329fc47da19.

Future-facing pass: the two smokes now keep separate owners for catalog evidence and README entry structure. No new abstraction is needed.

动机

精确 head 83cf792178da77bc31f0f6c5bd3ef61fbb4e8b94。当前主线 README 已更新定位文案，但 showcase catalog smoke 仍要求三处旧字串；基于同一主线的 #4945 checkout 实际以旧 tagline 的 AssertionError 退出。这条检查会阻断无关的 Frontstage Pages 构建。此 PR 是解除主线 CI 前置阻塞的独立、可回滚增量；它不代表投研团队产品旅程已验收。

改动思路

展示目录 smoke 继续负责公开案例链接、精选案例数量及证据目录；README 入口结构和当前“Recurring Work Presets”标题由既有 readme-demo-surface-smoke.py 检查。直接删去重复的精确文案断言，比把旧文案改成新文案更能避免下次编辑时同类失效。没有引入第二套规则或运行时状态。

具体改动

examples/showcase-catalog-smoke.py 仅删除三个断言：旧英文 tagline、旧产品定位句、旧 preset 标题；其余目录、案例与链接断言保留。没有生产代码、文档或生成文件变化。Frontstage Pages 工作流仍直接执行该 smoke。

对主干的风险

最主要的反例是未来 README 首屏内容变差而 catalog smoke 不再因精确措辞失败。该风险应由 README 入口检查和首屏 owner 预览承担，不能让目录测试冻结每次编辑文案。旧 checkout 对当前 README 的失败已复现；本 head 的 catalog smoke、README 入口 smoke、Pages 工作流 smoke、公开边界扫描和 diff 检查均通过。Goal 级 quick premerge 的 8 项检查通过，质量凭据 cqr_e10aec7a6329fc47da19 与本 head 匹配；无本地失败或手动 hold。本 Goal 的评审配置不等待远端 CI，因此这里不把 CI 状态当成已验证，也不据此授予合并权限。

我的整体评价

同意此精确 head 的测试修复。 这是三行删除、无运行时语义变化的合理收敛；同作者近期开放 PR 没有同形态 smoke 拆单。合并前仍须执行精确 head merge-readiness 与仓库合并规则，合并后重跑 #4945 的 Frontstage Pages；真实产品旅程验收继续保持开放。

English verdict: APPROVE - At 83cf792, the test-only deletion removes duplicated stale README copy checks while catalog and README entry coverage pass locally; merge readiness and the downstream Pages rerun remain separate gates.

Maintainer merge decision for exact head 83cf792178da77bc31f0f6c5bd3ef61fbb4e8b94: this PR changes only examples/showcase-catalog-smoke.py, deleting three stale, duplicated README copy assertions. The catalog links and case checks remain, and the separate README entry smoke retains the public-entry contract.

Local validation: catalog smoke, README entry smoke, Frontstage Pages workflow smoke, changed-file public scan, diff check, and goal-scoped quick premerge (8 selected/direct checks) passed. Exact-scope change-quality receipt cqr_e10aec7a6329fc47da19 is valid. Failures/skips: none in these required local checks. Manual holds: none. The Goal's review configuration does not consult remote CI, so CI is unverified here. The published author-owned COMMENTED review reaches APPROVE at this exact head; GitHub requires admin bypass because it cannot count self-approval. This test-only, single-purpose change is covered by the repository's small-PR self-merge policy. Post-merge, #4945 Frontstage Pages must be rerun; this merge does not accept the broader product journey.
