fix(browser): default non-finite vision config

[lin-hongkuan]

Summary

• reject non-finite browser vision timeout and temperature config values
• fall back to the existing 120s / 0.1 defaults for inf and nan
• add regression coverage for the regular browser vision path

Tests

• python -m pytest tests/tools/test_browser_console.py::TestBrowserVisionConfig::test_browser_vision_defaults_nonfinite_config -q
• python -m pytest tests/tools/test_browser_console.py::TestBrowserVisionConfig -q
• python -m pytest tests/tools/test_browser_console.py -q (fails on Windows due existing default-encoding reads of SKILL.md in TestDogfoodSkill; targeted browser vision tests pass)
• python -m py_compile tools/browser_tool.py
• python scripts/check-windows-footguns.py --all

Thanks for addressing the non-finite configuration case. The browser_vision change itself matches the current defect at tools/browser_tool.py:4118-4121 and the new test exercises the intended fallback.

Problems

• The same auxiliary.vision timeout/temperature parsing remains unguarded in image vision at tools/vision_tools.py:1236-1239 and video vision at tools/vision_tools.py:1739-1742. Those paths pass the converted values to their LLM calls, so nan/inf remains accepted outside browser_vision.

Suggested changes

• Apply finite-value validation to both tools/vision_tools.py paths, retaining their existing defaults, and add matching regression coverage.

Automated hermes-sweeper review.

Please extend this finite-value handling to the sibling auxiliary.vision consumers in tools/vision_tools.py (1236-1239 for image analysis and 1739-1742 for video analysis). They still pass nan/inf through direct float(...) conversions.
