Screen recording

New start_recording / stop_recording tools for capturing screen activity as MP4 video. Useful for recording UI flows, repro steps, and demo clips.

• Configurable FPS (default 5), region cropping, and max duration
• Supported on macOS (CGWindowListCreateImage) and Windows (BitBlt)

Windows feature parity

Windows now supports all tools that were previously macOS-only:

• Hover tracking — start_hover_tracking / get_hover_events / stop_hover_tracking via UI Automation and GetCursorPos
• Screen recording — start_recording / stop_recording via BitBlt capture loop
• element_at_point — added app_name scoping and container fallback
• find_text — now searches UIA Value and HelpText properties in addition to Name
• get_cursor_position — new Windows implementation via GetCursorPos

Fixes

• Drag pre-move cursor — cursor now moves to the start position before initiating a drag, ensuring correct start coordinates (Windows)
• Hover dwell accuracy — fixed dwell time calculation to use arrival/departure timestamps correctly, preventing inflated dwell values from pass-through elements
• Frontmost app detection — fixed macOS frontmost app resolution to use CGWindowList stacking order instead of NSWorkspace

Other

• Windows code refactored: deduplicated PID resolution, extracted text property helper, simplified capture_window_jpeg and UIA element search
• Updated rustls-webpki to 0.103.10 (CVE fix)
