v1.6.1

Patch release fixing scanner dependency version detection on Windows.

Closes #2.

Important packaging note:

• Operators should download Scan-PythonPackages_v1.6.1.zip, not a standalone .ps1 file.
• The release zip contains both required runtime files: Scan-PythonPackages.ps1 and inspect_binary.py.
• inspect_binary.py must remain beside Scan-PythonPackages.ps1; otherwise native PE/ELF binary inspection is skipped.

Fixed:

• Get-InstalledPackageVersion now uses the scanner venv Python executable with python -m pip show when checking installed scanner dependency versions.
• This avoids a Windows pip.exe wrapper failure mode after pip upgrades itself inside an existing .scan-venv.
• Existing scanner venvs no longer need to be deleted just to recover from the false bandit is not installed / version check failed path.

Changed:

• Scanner version metadata updated to 1.6.1.
• JSON report scannerVersion updated to 1.6.1.
• Changelog, README release-note pointer, fixture metadata, and v1.6.1 release notes updated.

Verification:

• Local fixture generation: passed.
• Local Pester: 51 passed, 0 failed.
• Added regression coverage for a broken pip.exe wrapper with successful python -m pip show bandit output.
