Ports ZIG/src/lib_vt.zig and terminal/c/* as crates/ghostty-vt-capi (cdylib + staticlib + rlib, soname libghostty-vt.so) implementing the unchanged include/ghostty/vt.h + vt/*.h ABI: OSC parser, SGR parser, key events and key encoding, paste safety, colors, result codes - all 38 native symbols, plus the ghostty_wasm_* helpers on wasm32. Verification: - tests/abi.rs generates a C probe from the headers, compiled with cc, that checks sizeof/alignof/offsetof of every struct/union, every enumerator and #define against Rust, and links every declared symbol; nm -D exports equal the declared functions. - Ghostty's example/c-vt* programs compile unchanged against the Rust library (shared and static) and produce the expected output. - The wasm32 build runs Ghostty's wasm-key-encode/wasm-sgr example scripts unmodified under node (upstream's wasm-sgr tag table is stale vs sgr.h; a regenerated copy checks full output). Test Plan: - cargo test -p ghostty-vt-capi (22 unit + 2 ABI + 5 C + 3 wasm tests)
