The Qt GUI was unused: out of make-app-release since March, not built by
the gate, and its app bundle could not start (no platform plugin). Every
renderer and input change had to be made in it separately. kge is the
ImGui frontend only.
Removes QtFrontend/QtInputHandler/QtRenderer, the KTE_USE_QT option and
its #if branches (Command.cc, GUITheme.h, main.cc), the Nix qt package
and dev shell, the commented-out Qt release steps, the Qt frontend plan,
and Qt mentions in AGENTS.md, DEVELOPER_GUIDE.md, REWRITE.md and code
comments. Git history keeps the code.

ImGui measured every span, highlight and the cursor from column 0 of the
line (and rescanned the line for each column conversion), which is
quadratic in line length on minified files. Columns now come from one
table per line and pixel offsets from the nearest position already
measured. Output is pixel-identical to before (compared under Xvfb, with
syntax colouring, tabs, UTF-8 and search highlights).
kte::kTabWidth replaces the literal 8s, and Qt's 4: Qt expanded tabs to
4 columns while the command layer scrolled by 8, misplacing the cursor
and horizontal scroll on lines with tabs. MeasureChar and
DisplayColumns (TermWidth.h) are the command layer's column model, now
shared, and Qt draws by it instead of one column per byte, which
shifted everything after a multi-byte character.
Qt also:
- drew operators in the dark-mode background colour, so they vanished;
- computed the editor's column count three ways (different glyph,
padding and status-row accounting) from painting, and positioned text
with a rounded cell width, so the cursor drifted off the glyphs on long
lines. One TextLayout now serves painting, resizing, font changes and
wheel scrolling, with a fractional cell width; runs are drawn only
where visible;
- drew each non-ASCII character at its cell, since a fallback-font glyph
wider than a cell pushed the rest of the run out of place.

Themes:
- Add leuchtturm theme (fountain pen ink on cream paper, brass/leather dark)
- Add per-theme syntax palettes for leuchtturm, tufte, and everforest
- Fix static inline globals giving each TU its own copy of gCurrentTheme
and gBackgroundMode (changed to inline for proper C++17 linkage)
- :background with no args now shows current mode
Font zoom:
- CMD-=/CMD--/CMD-0 to increase/decrease/reset font size

Warm cream paper, near-black ink, zero rounding, minimal chrome,
restrained dark red and navy accents following Tufte's design principles.

- 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.
