Fix: Windows compatibility for baoyu-post-to-wechat

## Problem
The baoyu-post-to-wechat skill failed on Windows due to:
1. `new URL(import.meta.url).pathname` returns incorrect path format on Windows
2. Copy/paste operations used `xdotool` (Linux tool) which doesn't exist on Windows

## Solution
1. **md-to-wechat.ts**: Use `fileURLToPath()` to correctly resolve file paths on Windows
2. **wechat-article.ts**: Use CDP `Input.dispatchKeyEvent` for copy/paste operations
   - Replaces system-dependent tools (xdotool/osascript)
   - Works consistently across Windows/macOS/Linux
   - More reliable as it operates within Chrome session

## Changes
- Import `fileURLToPath` from 'node:url'
- Replace `new URL(import.meta.url).pathname` with `fileURLToPath(import.meta.url)`
- Replace system tool calls with CDP keyboard events for Ctrl+C and Ctrl+V
- Add platform-specific modifier handling (Cmd for macOS, Ctrl for Windows/Linux)

## Testing
- Tested successfully on Windows 11
- Markdown conversion works correctly
- HTML copy/paste to WeChat editor works correctly
