fix(web): rewrite macOS clipboard implementation using C APIs
Replaces Objective-C implementation with pure C for Bun compatibility: **Key Changes**: - **Pure C Implementation**: Uses Core Foundation C APIs instead of Objective-C runtime - **Dynamic Loading**: Loads AppKit/Foundation frameworks via dlsym for runtime compatibility - **Fallback Strategy**: Gracefully falls back to pbcopy/pbpaste command-line tools if C APIs unavailable - **No Objective-C Dependencies**: Eliminates objc_msgSend and Objective-C runtime calls **Technical Implementation**: - CFStringRef/CFDataRef for Core Foundation string/data management - Dynamic symbol loading for NSPasteboard C functions - Proper memory management with CFRelease - Standard fork/exec for pbcopy/pbpaste fallback execution **Compatibility**: - Supports all macOS versions via fallback mechanism - Maintains same API surface as other platforms - Thread-safe async operations with std::thread - Consistent error handling across platforms The implementation now uses only C APIs that are officially supported by Bun's build system while maintaining full clipboard functionality on macOS. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
