[fern-api]

This PR regenerates code to match the latest API Definition.

---

Note

Removes model_name from Embed V2 APIs (hardcoded to marengo3.0 in raw clients), bumps SDK to 1.1.1, and updates assets/indexed-assets/multipart docs and types.

• Embed V2:
  • Remove model_name param from client.embed.v_2.create and client.embed.v_2.tasks.create; requests now include "model_name": "marengo3.0" in raw_client implementations.
  • Clarify input_type descriptions and add value lists; update usage snippets accordingly.
• SDK/versioning:
  • Bump SDK to 1.1.1 (pyproject.toml) and update headers (User-Agent, X-Fern-SDK-Version).
• Types/Models:
  • Update AssetStatus to {"failed","processing","ready"}; remove waiting.
  • Simplify Asset model: refine status doc; remove url/url_expires_at fields; keep core metadata.
  • Tweak CreateAssetUploadResponse.upload_urls notes and EmbeddingTaskResponse.status docs; adjust IndexedAsset.id doc; refine MediaSource.asset_id doc.
• Indexes/Assets/Multipart Upload:
  • Text-only doc refinements across assets, indexes.indexed_assets, indexes.videos (deprecated notices kept), and multipart_upload (phrasing, parameter descriptions, and notes).
• Docs/reference:
  • Remove custom <Note> blocks and tighten wording; adjust examples to match API changes.
• Dependencies:
  • Patch update exceptiongroup in poetry.lock.
