* fix(windows): prefer PowerShell for command execution Detect PowerShell 7 or Windows PowerShell before falling back to cmd.exe, and share the selected host shell across agent tools and the interactive shell escape. Configure UTF-8 output, preserve restricted-sandbox MSYS safeguards, and add Windows coverage for pipelines, workspace writes, and interactive stdin sessions. * test(windows): align shell coverage with PowerShell Make Windows command fixtures and guidance assertions follow the selected host shell, preserve cmd fallback coverage, and use a genuine MSYS executable when PowerShell aliases are available. Remove the unsupported non-TTY PowerShell stdin assertion; Windows interactive stdin requires a separate PTY transport. * fix(sandbox): classify Windows executable suffixes Normalize .exe, .cmd, .bat, and .com command names before safety and network lookup so PowerShell invocations such as curl.cmd receive the same network permission handling as curl. Add analyzer and engine-level regressions for the Windows PowerShell command shape observed in CI. * fix(sandbox): normalize absolute Windows command paths Extract drive-letter and UNC basenames before removing shell escape characters so fully qualified Windows executables continue matching canonical safety and network classifications. Cover both drive and UNC curl paths with analyzer regressions. * fix(sandbox): normalize relative Windows paths Recognize drive-relative, explicit relative, and suffixed backslash executable paths before generic shell escape removal so Windows commands continue to match canonical sandbox risk entries. * fix(windows): harden PowerShell execution * fix(sandbox): classify PowerShell removal aliases
