fix(smokes): cover new goal configuration catalog features

[songoow]

Summary

• examples/project/configure-goal-smoke.py asserted an exact default-off feature set that no longer matches the goal configuration catalog: local_authority_shadow (Stage 2C, feat(control-plane): add Stage 2C local authority cutover kernel #3882) and periodic_report (feat(machine-config): add generic operator configuration surfaces #3865 / feat: unify machine and Goal capability configuration #3910) are now reported, so the smoke fails on shard 3 of Full Public Smokes on every main head since 343b5f972.
• Extend the expected set and assert the never-opted-in defaults from the feature semantics, not from the observed output: local_authority_shadow is experimental_opt_in with current == {"enabled": false, "mode": null, "status": "disabled"} and a preview/apply --execute contract; periodic_report is supported_explicit_override, default {"enabled": false, "timezone": "UTC"}, and intentionally carries no current key while the Goal has no override (the configuration UI already treats it as optional).
• Smoke-only change. It guards the shipped default-off disclosure of two real capabilities; no runtime, CLI, or default behavior changes.

Companion baseline PRs for the other shard failures: #3943 (concise help and manpage parity) and #3944 (todo.py owner extraction). Each is independent and can merge in any order.

结论：REQUEST CHANGES。

1. 变更范围与价值

这个 PR 只扩展 examples/project/configure-goal-smoke.py，把已经进入统一 goal configuration catalog 的 local_authority_shadow 和 periodic_report 纳入 durable smoke。这里不是单纯重复 capability 自身测试：它守住的是统一 configure-goal 发现面上的 feature 集合、default-off 语义、current 值以及 preview/apply/verify 命令形态，因此有实际的回归价值。

2. 设计检查

新增断言与两个能力的公开契约一致：local_authority_shadow 保持 experimental_opt_in、默认关闭，preview 不带 --execute 而 apply 带；periodic_report 保持 supported_explicit_override、默认关闭，并且未设置 goal override 时不伪造 goal-scoped current。没有看到扩大普通用户默认行为或隐式启用能力的问题。

3. 独立验证

我在 exact head 81ebb03daf17d13c1ccf59df74144b6760cb1c9b 上运行了 configure-goal smoke，结果为 configure-goal-smoke ok；py_compile 与 git diff --check 也通过。DCO、dependency review、Windows 和 Sonar 检查均为通过。

4. 阻塞项

当前 required pytest 仍然失败。唯一失败是 tests/capabilities/test_pr_review_contract.py::test_execution_contract_owns_deep_review_requirements：基线文本仍为 Flag silent changes ...，而测试要求包含精确语义 silent behavior changes。这与本 PR 的 smoke diff 无关，修复已位于尚未合入的 #3940，但在本 exact head 上 required CI 仍为红色，因此现在不能批准。

5. 建议下一步

请等待 #3940 合入后 rebase 到最新 main，重新触发 required pytest；如果 exact head 的 required checks 全绿且本变更保持不变，即可重新评审。

English verdict: REQUEST CHANGES — the smoke additions are well-scoped and independently pass, but the exact head still has a failing required pytest check; rebase after #3940 lands and rerun CI.

Rebased onto official main@b2cf4312d (which now carries #3940). New exact head dcab9394d. Mechanical rebase only: git range-diff against the reviewed head 81ebb03da reports zero non-identical commits, and configure-goal-smoke still passes locally. Required checks are re-running on this head.
