Ports apprt/embedded.zig, main_c.zig and config/CApi.zig + c_get.zig as crates/ghostty-lib (cdylib/staticlib/rlib `libghostty`), exporting every function of the unchanged include/ghostty.h - the ABI Ghostty's Swift macOS/iOS app links against. The embedded runtime implements the runtime traits over the host's C callbacks, so the real core drives it. - ghostty-core selects the renderer per target: Metal on Apple (surface NSView/UIView via RtSurface::platform_view), OpenGL elsewhere. - ghostty_config_get follows Zig's c_get rules via a CValue type (143 supported keys, checked against the Zig field types). - The inspector C API is complete; its Metal backend replaces ImGui's Metal renderer and has not run. Verification: generated C ABI probe (sizeof/alignof/offsetof of every struct/union, 755 enum values, every function linked, nm exports, headers byte-identical to upstream); a C host on Linux covering init, CLI actions, config, app, keys, focus and color scheme; an opt-in test-platform feature creating real surfaces on Linux with headless EGL and a pty (13 tests). Apple targets are clippy-clean but not run; the Swift app has not been built against it. Test Plan: - cargo test -p ghostty-lib (and --features test-platform) - cargo clippy --target aarch64-apple-darwin -p ghostty-lib (cross env in docs/rewrite/notes/macos-M1.md)

//! The C representation of config values (Zig: `config/c_get.zig` together

//! `ghostty_config_get` writes a value of a key-dependent C type into a

//! value is described by [`CValue`] and the C API crate (`ghostty-lib`) does
|

//! the actual write.
