## Why [#21736](https://github.com/openai/codex/pull/21736) introduces the typed extension API, but the runtime does not yet carry a registry through thread/session startup or give contributors host-owned stores to read from. This PR wires that host-side path so later feature migrations can move product-specific behavior behind typed contributions without adding another bespoke seam directly to `codex-core`. ## What changed - Thread `ExtensionRegistry<Config>` through `ThreadManager`, `CodexSpawnArgs`, `Session`, and sub-agent spawn paths. - Wire `ThreadStartContributor` and `ContextContributor` - Expose the small supporting surface needed by non-core callers that construct threads directly, including `empty_extension_registry()` through `codex-core-api`. This PR lands the host plumbing only: the app-server registry is still empty, and concrete feature migrations are intended to follow separately.
