- C0 controls and DEL were passed to ncurses, which acted on them: a
carriage return moved to column 0 and the line padding then erased
the text, so every line of a CRLF file drew blank, and a backspace
ate the previous character. They are now drawn in caret notation
(^M, ^H, ^?) and counted as two cells. C1 controls (and stray bytes
0x80-0x9F, which decode to them; U+009B is CSI) are drawn as '?'.
- The width rule lives in TermWidth.h and is shared by the renderer's
drawing loop, its cursor placement and the command layer's
horizontal scrolling and mouse mapping, which also disagreed on NUL
and invalid bytes.
- GUI config: columns/rows must be 1..1000 and the font size a finite
4..200 (TOML 'size = inf' and huge values were accepted, leading to
UB in float-to-int conversion and int overflow downstream).
Verified in tmux: a CRLF file now shows 'first line^M' where the
baseline showed a blank line.
Audit findings B9 (and the CR/BS case from the follow-up review).

The edit-mode font switcher called LoadFont() directly between
NewFrame() and Render(), invalidating the font atlas ImGui was
actively using. Use RequestLoadFont() to defer the change to
the safe inter-frame point, matching the existing zoom pattern.
Also default code_font/writing_font to the main font when not
explicitly configured, preventing a mismatch that triggered the
switch on every first frame.

- Add three proportional serif fonts: Crimson Pro, ET Book, Spectral
- Fix text rendering for variable-width fonts: selection, cursor,
mouse click mapping, search highlights, and syntax-colored text
now use pixel-accurate measurement via ImGui::CalcTextSize()
- Add per-buffer edit mode (code/writing) with auto-detection from
file extension (.txt, .md, .rst, .org, .tex default to writing)
- Add C-k m keybinding and :mode command to toggle edit modes
- Switch config format from INI to TOML (kge.toml), with legacy
INI fallback; vendor toml++ v3.4.0
- New config keys: font.code and font.writing for per-mode defaults
- Add font tab completion for ImGui builds
- Add tab completion for :mode command
- Update help text, themes.md, and add CONFIG.md
- Bump version to 1.10.0
