SearchHighlight compiles the search pattern once per frame and yields each line's match ranges; the terminal, ImGui and Qt renderers had three copies of this, and Qt compiled a std::regex for every visible line on every frame. Qt now uses kte::Regex like the others. kte::Regex::RunGuarded replaces Command.cc's run_regex_work, which chose the large stack by comparing engine names. ForEachRegexMatch had no callers left and is removed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015rcVQiiWyTzoNrsvLSaAfB
