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.

Defer edit-mode font switch to next frame via RequestLoadFont() to
avoid modifying the locked ImFontAtlas between NewFrame() and Render().
Rework Nix packaging: split nativeBuildInputs/buildInputs correctly,
add devShells for nix develop, desktop file for kge, per-variant pname
and meta.mainProgram, and an overlay for NixOS configs.

1. Static linking - Added KTE_STATIC_LINK CMake option and
disabled it in default.nix to avoid the "attempted
static link of dynamic object" error
2. Missing include - Added <cstring> to
test_swap_edge_cases.cc for std::memset/std::memcpy (GCC
14 is stricter about transitive includes)
- Updated `make-app-release` script to use `macdeployqt` with proper verbosity and bundle fixup.
- Introduced post-build fixup using CMake's `BundleUtilities` to internalize non-Qt dylibs.
- Enhanced macOS bundle RPATH settings for accurate Framework resolution.
- Added optional `kge_fixup_bundle` CMake target for post-build handling.
- Refined `default.nix` to load Nixpkgs in a default argument.
- Added `QtFrontend`, `QtRenderer`, and `QtInputHandler` for Qt-based UI rendering and input handling.
- Implemented support for theming, font customization, and palette overrides in GUITheme.
- Renamed and refactored ImGui-specific components (e.g., `GUIRenderer` -> `ImGuiRenderer`).
- Added cross-frontend integration for commands and visual font picker.
