Remove macOS-only guards so Computer Use works cross-platform:
- main.tsx: allow CHICAGO_MCP on any known platform (not just macos)
- swiftLoader.ts: remove darwin-only throw, let the backend handle it
- computer-use-input: dispatch to darwin/win32/linux backends
- computer-use-swift: rename loadDarwin→loadBackend, dispatch all platforms

Two root causes fixed:
1. swiftLoader.ts: require('@ant/computer-use-swift') returns a module
with { ComputerUseAPI } class, not an instance. macOS native .node
exports a plain object. Fixed by detecting class export and calling
new ComputerUseAPI().
2. executor.ts resolvePrepareCapture: toolCalls.ts expects result to have
{ hidden: string[], displayId: number } fields. Our ComputerUseAPI
returns { base64, width, height } only. Fixed by backfilling missing
fields with defaults.
Verified: request_access → screenshot → left_click all work on Windows.

New Windows-native capabilities:
- windowCapture.ts: PrintWindow API for per-window screenshot (works on
occluded/background windows)
- windowEnum.ts: EnumWindows for precise window enumeration with HWND
- uiAutomation.ts: IUIAutomation for UI tree reading, element clicking,
text input, and coordinate-based element identification
- ocr.ts: Windows.Media.Ocr for screen text recognition (en-US + zh-CN)
Updated win32.ts backend to use EnumWindows for listRunning() and added
captureWindowTarget() for window-specific screenshots.
