Preserve discriminator in partial PATCH models (#1401)

---

Note

High Risk
Upstream flagged a breaking API change: callers must migrate from string modes and flat viewport/page fields to discriminated mode objects or requests will fail or misconfigure browsers.

Overview
Bumps hai-agents to 1.0.1 (User-Agent headers, lockfile) and renames the OpenAPI product title to Computer-Use Agents.

Breaking: browser environment configuration no longer uses a top-level mode string (visual / text / multimodal) plus separate width, height, and page_chars on the browser spec. Those settings now live on a discriminated mode object (type: visual | text): visual carries viewport width/height and a markdown flag (replacing multimodal); text uses chunk_size (replacing page_chars). The same shape applies to PATCH environment updates via PatchEnvironmentMode_* variants.

Generated SDK surface changes: new BrowserTextMode / BrowserVisualMode types, environment create/update/patch clients drop the old scalar parameters and serialize mode through the union helpers; package exports and spec-default tests are updated for dropped type discriminator fields on the mode schemas.
