Ports the macOS-specific Zig code behind cfg(target_os = "macos"): - renderer: a GraphicsApi trait with generic::Renderer<G>; Metal backend (all renderer/metal/* files, shaders.metal verbatim, runtime library compile, IOSurface layer, CVDisplayLink), shadertoy -> MSL via naga; OpenGL remains the backend elsewhere. - font: CoreText face, shaper and discovery with build.rs backend selection (coretext default; coretext-freetype / coretext-harfbuzz / coretext-noshape features), no fontconfig/freetype/harfbuzz on Apple. - input: KeymapDarwin via UCKeyTranslate, option-as-alt, mac keycodes. - os: macos, mach, cf_release_thread, NSProcessInfo args and macOS branches; config: macOS defaults, keybinds, Application Support paths. - termio/core: login(1) wrapping, openpty/execvpe, Darwin child exit handling, os_log logging. Compile-checked for aarch64/x86_64-apple-darwin (clippy -D warnings clean) using the cross setup in docs/rewrite/notes/macos-M1.md; cannot run here. The embedded runtime/C API (embedded.zig) is the next step. Also includes the cross-platform integration edits shared by the crash, verification, Windows and macOS work (Cargo target-gating, thread crash-context hooks, apprt-gtk surface/IME refactor, termio/os cfg gates), a cfg fix so ghostty-config builds on wasm32, and an allow for the intentional recursion in the crash overflow test. Test Plan: - cargo test --workspace (3224 passed) - cargo clippy --workspace --all-targets -- -D warnings - cargo check --target aarch64-apple-darwin -p ghostty-renderer (with the documented cross env)
