docs(plugin): refocus the certification page on developer decisions

Rewrite plugin/certified-plugins in all three locales around the
questions a plugin developer actually asks, and make it the single home
for certification: what it is, why it exists, when it is needed, what
changes after approval, and what the contract requires.

- Decision framing restored, including a needs/does-not-need table and
  the explicit statement that most plugins do not need certification.
- Full manifest example, accepted values for both declaration fields and
  the SDK version that recognises them.
- Constraints kept and tightened: stateless rules, allowed/forbidden
  table, anti-patterns with correct/incorrect snippets, Runner notes,
  self-check list.
- Submission flow moved onto this page so it no longer depends on the
  publishing page.
- Operator content that duplicates the Core architecture document
  removed (Cloud admission matrix, OSS issuer keys, certificate fields,
  internal review tiers).

publish/market is now publishing-only with a one-line pointer, and its
misplaced plugin_submission screenshot moves back under the upload
section where it belongs. dev/basic-info replaces the commented-out
manifest fields with a link to the contract page.

ja had been missing whole sections (36 lines); all three locales now
share the same section structure.

-## 申请认证插件审核
-
-如果该版本准备申请认证，请在 `manifest.yaml` 中同时声明 `execution.sharedRuntime: shared-runtime-v1` 和 `execution.componentModel: stateless-v1`，并提交一个**新版本**。辅助审查会确认单例组件无状态、可重入、按调用读取配置且不持有租户数据。声明本身不会授予认证标识或共享运行权限。
-
-LangBot Space 会检查本次提交的精确插件包，进行辅助代码审查，并在人工批准后才签发认证插件标识。认证绑定到已审核的插件版本与校验和。请让工作区配置、存储、凭据、日志和后台工作都与当前安装绑定，不要依赖可变的进程全局状态。
-
-如果审核发现该版本无法满足要求，请先作为未签名的普通专属插件提交，并在后续不可变版本中修复问题。不存在专属运行认证或中间认证等级。用户侧说明见[认证插件](/zh/plugin/certified-plugins)。
