Subject: [PATCH] fix: open HTML report in Windows browser when running in WSL

WSL users currently see a broken popup when TrendRadar tries to open
the HTML report, because Python's webbrowser.open() launches a Linux
browser that has no display. This fix detects the WSL environment and
uses PowerShell's Start-Process to open the report in the user's
Windows default browser instead.

Changes:
- Add _is_wsl() to detect WSL via /proc/version
- Add _open_in_windows_browser() using wslpath + powershell.exe
- Non-WSL environments are unaffected
