Ports the parsing half of ZIG/src/terminal into the ghostty-vt crate: - Parser state machine with a compile-time generated parse table and the UTF-8 decoder - OSC parser incl. all sub-parsers (titles, colors, clipboard, hyperlinks, semantic prompts/OSC 133, OSC 9 / ConEmu, iTerm2, kitty clipboard, color and text-sizing protocols, context signals) - CSI, SGR, modes table with save/restore, charsets, ansi, device status, mouse shapes, APC, DCS (incl. XTGETTCAP), tmux control-mode parser - color palette / X11 color names, kitty color and graphics command parser Deviations from Zig (documented in docs/rewrite/notes/ghostty-vt-W*.md): parser actions own their payloads instead of borrowing parser buffers; OSC strings are Vec<u8>; non-exhaustive Zig enums gain an Other(raw) variant; tmux regexes replaced by equivalent hand-written matchers. Known follow-up: semantic_prompt.rs carries local copies of the printf-q and percent decoders that belong in ghostty-os. Test Plan: - cargo test -p ghostty-vt: 395 passed, 1 ignored (skipped in Zig too) - cargo clippy -p ghostty-vt --all-targets -- -D warnings: clean
