## What changed
Add an optional `onboardingSkill` summary to `plugin/read` responses and update the generated schemas, TypeScript types, and Python models.
- Resolve local declarations from `extensions["com.openai"].onboardingSkill`, accepting relative paths with or without `./`. Require the resolved path to stay within the plugin root and match a loaded skill.
- Match remote release metadata's `onboarding_skill_name` against the plugin's skills.
- Return the summary only when the plugin and matching visible skill are enabled; remote plugins must also be available. Otherwise, return `null`.
## Testing
Add parameterized local and remote `plugin/read` tests covering matching, missing, and unmatched declarations, disabled plugins and skills, and unavailable remote plugins.

## What changed
- Recognize root `plugin.json` files using the Agent Plugins 1.0 schema and map their portable metadata, `skills/`, and `mcp.json` into Codex plugin manifests.
- Apply Codex-specific apps, hooks, and interface settings from the inline `com.openai` extension, with `.codex-plugin/plugin.json` as a fallback overlay.
- Preserve legacy manifest precedence when a root `plugin.json` is unrelated, and reject unsupported Agent Plugins schema versions.
- Add a direct-child skill discovery mode that excludes nested skills and paths resolving outside the plugin root.
## Testing
- Cover manifest metadata, validation, extension precedence, legacy fallback, and direct-child skill path boundaries.
