Integrate wingather utilities: Authenticode verification + window management

[djdarcy]

Summary

The wingather project contains reusable code that could strengthen the DazzleLib ecosystem:

1. Authenticode signature verification (~40 lines) — natural fit for dazzle_filekit.verification
2. Window management platform layer (~720 lines) — candidate for a new DazzleLib package (dazzle-winutil)

Authenticode Verification (fits in dazzle-filekit)

wingather has a batch Authenticode signature verification function that uses PowerShell to verify digital signatures on Windows executables. This fits naturally alongside the existing hash verification in dazzle_filekit.verification.

Proposed API:

from dazzle_filekit.verification import verify_authenticode

results = verify_authenticode(["C:/Windows/notepad.exe", "C:/suspect.exe"])
# Returns dict of path -> {valid: bool, signer: str, ...}

Window Management Library (new package)

wingather's platform abstraction layer is clean, generic, and immediately reusable:

• WindowInfo — platform-agnostic window metadata
• PlatformBase — abstract interface for window operations
• WindowsPlatform — Windows implementation (monitors, DPI, virtual desktops, window manipulation)
• VirtualDesktopHelper — COM virtual desktop interface

This could become dazzle-winutil under the DazzleLib org, expanding the ecosystem into window/display management.
