What I did

Document the experimentalDocgenServer feature flag in the main config features API reference.

• Add the flag to the React-only features type block and a new section covering server-side docgen, static snippets, manifest/MCP benefits, and tradeoffs
• Add config snippets (main-config-features-experimental-docgen-server.md) for CSF 3 and CSF Next
• Cross-link from componentsManifest, experimentalCodeExamples, and the manifests guide
• Link to the Docgen Server RFC

Manual testing

Caution

This section is mandatory for all contributions. If you believe no manual test is necessary, please state so explicitly. Thanks!

1. Open the docs preview for this branch (or run the docs site locally if needed).
2. Navigate to Configure → main.js|ts → features with the React renderer selected (?renderer=react).
3. Confirm a new experimentalDocgenServer section appears before experimentalCodeExamples, with the Experimental badge, default false, and a working code snippet.
4. Confirm the componentsManifest section mentions the ref-based manifest format when combined with docgen server.
5. Confirm experimentalCodeExamples recommends experimentalDocgenServer instead.
6. Open AI → Manifests with the React renderer and confirm the one-line note about server-side React Component Meta extraction.
7. Spot-check that the RFC feedback link is present as a placeholder (discussions/TODO) for a follow-up once the GitHub Discussion is opened.
