RegexEngine.h/.cc wrap the regex engine for search, regex replace-all and the terminal and ImGui renderers' match highlighting: - With KTE_USE_PCRE2 (default ON; used when pkg-config finds libpcre2-8, linked as -lpcre2-8) patterns are compiled by PCRE2 with its JIT and matched under a match limit: catastrophic backtracking stops with a status note instead of hanging the editor, and matching does not recurse on the C stack (no large-stack thread; the per-keystroke and per-frame line limit is 1 MiB instead of 2,000 bytes). Otherwise std::regex is used as before. - Replacement strings follow std::regex_replace (ECMAScript as libstdc++ reads it) with either engine: the PCRE2 path expands $&, $n, $`, $', $$ itself and steps over empty matches the same way. - Regex search walks lines over the materialized text instead of calling GetLineView per row. The terminal renderer compiles the pattern once per frame (it compiled it for every row). - Only one checkpoint per journal is queued at a time: whole-file edits in a row on a large buffer each queued a full copy of the buffer. - default.nix and the Dockerfile add pcre2 and pkg-config. On 26 MB: regex keystroke 1.6 -> 0.14 ms, next 62 -> 6 ms, replace-all 929 -> 438 ms; a rarely matching regex over 105 MB: 1.55 s -> 0.10 s.
