Pull request overview

This PR updates the functional-test resource monitoring utilities to better support LLM long-tests focused on memory usage, including additional memory breakdown metrics and Windows support.

Changes:

• Extend Docker resource monitoring to capture additional memory metrics (private/anon vs cache) and add an efficient “sample all metrics” path.
• Introduce a Windows resource monitor that collects process memory stats via PowerShell and writes them to artifacts.
• Update OVMS run context to attach the correct resource monitor depending on Docker vs Windows execution.
