feat: enable Computer Use with Python bridge replacing private native modules

Bypass all three gating layers (compile-time feature flag, subscription
check, GrowthBook remote config) and replace Anthropic's private native
modules (@ant/computer-use-swift, @ant/computer-use-input) with a Python
bridge using pyautogui + mss + pyobjc. Works on any macOS with any
Anthropic-protocol compatible model.

+## Computer Use Desktop Control
+
+This project enables and modifies Claude Code's Computer Use feature (internal codename "Chicago"), allowing AI models to directly control your macOS desktop — screenshots, mouse clicks, keyboard input, app management.
+
+**Underlying modification**: The official implementation depends on Anthropic's private native modules (`@ant/computer-use-swift`, `@ant/computer-use-input`). This project replaces them entirely with a Python bridge using `pyautogui` (mouse/keyboard), `mss` (screenshots), and `pyobjc` (macOS APIs) — no closed-source binaries required.
+
+```bash
+# Ensure Python 3 and macOS Accessibility/Screen Recording permissions, then:
+./bin/claude-haha
+> Take a screenshot
+> Open Safari and search for something
+```

+For supported platforms, technical architecture, and approaches we tried, see: **[Computer Use Guide](docs/computer-use.en.md)**

 ## Fixes Compared with the Original Leaked Source
 
 The leaked source could not run directly. This repository mainly fixes the following issues:
