ci(python): drop PR labeled trigger for python-release dry-run

Remove the pull_request:[labeled] trigger from python-release.yml so the
workflow no longer fires (and shows a gray skipped check) when a PR gets any
non-dry-run label. The credential-free dry-run validation is now manual-only
(workflow_dispatch with publish=false), preserving the validation capability
without a PR gray segment.

- python-release.yml: on is workflow_dispatch only; build.if is
  github.event_name == 'workflow_dispatch'.
- ci-workflow.spec.ts: assert python-release has no pull_request event and the
  simplified build.if.
- python/development.(md,zh.md) and 2026-08-11-python-publication-workflow note
  (en/zh/i18n): describe the manual dispatch-only dry-run path.

Verification: ci-workflow.spec.ts 14/14, typecheck clean, note-format 585,
verify-translation-pairing consistent.

 ## Decision
 
-The `Release (Python)` GitHub workflow exposes credential-free validation to pull requests labeled `python-release-dry-run` and to manual runs with `publish=false`. Both paths call the native wheel builder for all three platforms, install the Linux release set on Python 3.10 and 3.14, download the four resulting artifacts, verify their exact filenames and package metadata, enforce PyPI's default per-file size limit, record SHA-256 hashes, and retain one aggregate release candidate. These jobs have only repository read permission and no registry credential or OIDC permission, and pull request events cannot enter either publication job.
+The `Release (Python)` GitHub workflow exposes credential-free validation to manual runs with `publish=false`. The run calls the native wheel builder for all three platforms, installs the Linux release set on Python 3.10 and 3.14, downloads the four resulting artifacts, verifies their exact filenames and package metadata, enforces PyPI's default per-file size limit, records SHA-256 hashes, and retains one aggregate release candidate. These jobs have only repository read permission and no registry credential or OIDC permission, and a dry-run run cannot enter either publication job.
 
 A run with `publish=true` must use the `python-v<repository-version>` tag in the private automation repository, match that repository's `github.repository` to its repository-scoped `PYPI_PUBLISHER_REPOSITORY` variable, find `PUBLIC_PYPI_RELEASE_ENABLED=true`, and receive approval from the `pypi-runtime` and `pypi` GitHub environments for runtime and SDK publication, respectively. The read-only public mirror supplies the package metadata URLs but does not run release Actions. Only the two publication jobs receive `id-token: write`; PyPI Trusted Publishing exchanges the private repository identity for short-lived project credentials, so the repository stores no PyPI token.

 设置 `publish=true` 时，运行必须在私有自动化仓库使用 `python-v<repository-version>` 标签，将该仓库的 `github.repository` 与其仓库级 `PYPI_PUBLISHER_REPOSITORY` 变量匹配，找到 `PUBLIC_PYPI_RELEASE_ENABLED=true`，并分别获得 GitHub `pypi-runtime` 和 `pypi` 环境对运行时与 SDK 发布的批准。只读公开镜像提供包元数据 URL，但不运行发布 Actions。只有两个发布作业获得 `id-token: write`；PyPI Trusted Publishing 会把私有仓库身份换成短期项目凭据，因此仓库不保存 PyPI token。

 Public publication runs from the private automation repository; package metadata points to the separate read-only public source mirror, which does not run release Actions. The private repository defines the repository variable `PYPI_PUBLISHER_REPOSITORY` as its own `owner/name` and keeps `PUBLIC_PYPI_RELEASE_ENABLED=false` except during an intentional release.
