ghostty-unicode: Ghostty computes codepoint properties with the uucode Zig package (v0.2.0, Unicode 17.0.0). There is no Rust equivalent, so a trimmed UCD set is vendored in ucd/ and build.rs re-implements uucode's derivations: cell width rules incl. Ghostty's overrides for emoji modifiers and Prepend, grapheme break classes with the compile-time grapheme_break state table, the is_symbol set, and emoji presentation. Lookups are three array indexes per codepoint. Validated against the official GraphemeBreakTest.txt. ghostty-datastruct: split_tree (used for GTK splits; f16 ratios so rounding and debug diagrams match Zig), circ_buf, lru, cache_table, blocking_queue, segmented_pool, message_data, comparison, array_list_collection. intrusive_linked_list is not needed (lru is index based). lru now reports the evicted (old) key, Zig reported the new key, which appears to be a bug. Not yet covered: case_folding_full (needed by input bindings). Test Plan: - cargo test -p ghostty-unicode (16) -p ghostty-datastruct (88) - cargo clippy for both crates with -D warnings
