Bump browser-use to 0.13.8 in Python template

[dprevoznik]

Summary

• Bumps the browser-use dependency floor from >=0.11.1 to >=0.13.8 in the kernel create --template browser-use Python template
• Re-locks uv.lock so uv sync picks up 0.13.8 instead of resolving to the previously-frozen 0.11.1
• No code changes needed in main.py / session.py — the Browser/Agent constructor surface (cdp_url, headless, window_size, viewport, device_scale_factor) is unchanged across these releases

Test plan

• uv lock --upgrade-package browser-use resolved cleanly to 0.13.8
• uv sync installed the template's dependency set without conflicts
• Ran the template's main.py flow (Kernel browser -> Browser(cdp_url=...) -> Agent(...).run()) end-to-end against a live Kernel cloud browser; agent navigated to example.com and correctly extracted the page title

Note

Low Risk
Sample-template dependency and lockfile updates with removal of obsolete workaround code; behavior change risk is mainly from the large kernel SDK version jump, which the author exercised end-to-end.

Overview
Updates the browser-use Python Kernel template to browser-use>=0.13.8 and kernel>=0.97.0, with uv.lock refreshed for the new resolution tree.

Because newer browser-use handles CDP viewport/window sizing correctly, the template drops session.py and the BrowserSessionCustomResize workaround that existed for older releases. main.py only loses a stale commented alternative for browser_session; the live path still uses Browser(cdp_url=...) and Agent(..., browser_session=browser).

No blocking findings.

Verified the regenerated lockfile against pyproject.toml, installed the locked environment on Python 3.11, checked package compatibility, imported and constructed the updated Browser Use and Kernel SDK surfaces, scaffolded the template, and ran the CLI test suite.

Non-blocking follow-up: pkg/templates/python/browser-use/session.py is an obsolete compatibility shim for Browser Use versions below 0.7.9 and can be deleted separately.

@masnwilliams i am actually going to remove this too. good callout

Removed the obsolete session.py compat shim (browser-use < 0.7.9) in 2557974 — addresses @masnwilliams's follow-up.
