feat(snap-happy): Windows/WSL2 support and MCP tool annotations

[bryankthompson]

Summary

I've developed comprehensive Windows and WSL2 support for snap-happy, along with MCP tool annotations. These changes are currently in my standalone fork at triepod-ai/snap-happy-mcp.

Features Added

1. Windows/WSL2 Support

• WSL2 detection via WSL_DISTRO_NAME environment variable
• Automatic path conversion from WSL paths (/mnt/c/) to Windows paths (C:\)
• Window-specific capture on Windows using PrintWindow Win32 API via PowerShell
• ListWindows on Windows - enumerates visible windows with handles
• PowerShell temp script handling with proper cleanup

2. MCP Tool Annotations

Added annotations to all three tools per MCP specification:

Tool	title	readOnlyHint	destructiveHint	idempotentHint	openWorldHint
GetLastScreenshot	"Get Last Screenshot"	true	-	-	false
TakeScreenshot	"Take Screenshot"	false	false	false	false
ListWindows	"List Windows"	true	-	-	false

Current Upstream Limitation

The upstream currently only supports full-screen capture on Windows/Linux, with window-specific capture limited to macOS.

Contribution Approach

Since my fork is a standalone repo and this is a monorepo, I can't create a direct PR. I'm happy to:

1. Provide patches/diffs for manual integration
2. Fork this repo and create a proper PR with the changes ported over
3. Collaborate on integration in whatever way works best
