Compile and run C in JavaScript

Bun, a JavaScript runtime, now supports compiling and running native C code directly from JavaScript. This new feature, introduced in version 1.1.28, offers an alternative to existing methods like N-API addons and WebAssembly. It uses TinyCC to compile C programs in-memory, with fast compilation times (around 5ms) and low overhead (2ns per call). This approach allows developers to use C libraries and system APIs from JavaScript without separate build steps or complex setups. It's particularly useful for tasks like video conversion with ffmpeg or accessing system-specific features like the macOS Keychain API.
