docs: remove browser-use custom resize workaround

[dprevoznik]

Summary

• Removes the callout in the Browser Use integration guide documenting the BrowserSessionCustomResize workaround for viewport sizing on Browser Use < 0.7.9
• No longer needed since newer Browser Use versions handle viewport sizing correctly

Test plan

• Docs-only change, verified no other references to the workaround remain in the repo

---

Note

Low Risk
Documentation-only deletion with no runtime or API impact.

Overview
Removes the Browser Use integration callout that told users to apply the BrowserSessionCustomResize workaround when running Browser Use versions below 0.7.9 for correct viewport sizing.

That guidance is obsolete because current Browser Use releases handle viewport sizing without the custom session hook, so the doc no longer mentions the workaround.

Risk assessment: Very Low

Verdict: Prior approval stands. Risk did not increase after this update. Not re-approving.

Re-evaluated after the synchronize that merged main into this branch (6249449).

What the branch originally changed

• 242839b deleted a 12-line <Info> callout in integrations/browser-use.mdx (the Browser Use < 0.7.9 BrowserSessionCustomResize workaround).
• Single documentation file. No application code, APIs, auth, billing, CI, navigation (docs.json), or infrastructure edits.
• No CODEOWNERS file in this repo.

What this update did

• Merge commit 6249449 only brought main in (auth/react.mdx from #534).
• #534 already applied the same 12-line deletion to integrations/browser-use.mdx on main.
• Three-dot and two-dot diffs vs main are now empty (GitHub: 0 files changed). The trees match.

Why Very Low (unchanged)

• Current unique diff vs main is empty — no remaining production, docs, or infra delta.
• Prior unique change was documentation-only and already shipped via #534.
• No new codepaths, shared systems, or security surface.

Approval

• This automation already approved HEAD 6249449.
• Risk is still Very Low (if anything narrower: no-op vs main).
• Approval is not dismissed and is not re-issued.

This PR no longer has a unique change set. Closing it is the clean follow-up; merging it is a no-op.
