On macOS GUI builds, chdir(HOME) runs before deferred file opens are
processed, breaking relative paths passed on the command line. Resolve
each argv path to absolute immediately during argument parsing.
Bump version to 1.11.2.

apply_syntax_to_buffer() was called every frame and unconditionally reset
edit mode from the file extension, making it impossible to toggle out of
writing mode for .txt/.md files. Add edit_mode_detected_ flag to Buffer so
auto-detection runs once per buffer. Writing mode now also disables syntax
highlighting as intended. Propagate edit_mode_ through Buffer copy/move ops.

The GUI renderer had two competing horizontal scroll systems: a
character-based one (coloffs × space_w) and a pixel-based one. For
proportional fonts the character-based system used "M" width to
calculate viewport columns, triggering premature scrolling at ~50%
of the actual display width.
Switch the GUI renderer to purely pixel-based horizontal scrolling:
- Remove coloffs↔ImGui scroll_x bidirectional sync
- Measure rx_to_px from column 0 (absolute) instead of from coloffs
- Draw full expanded lines; let ImGui clip via its scroll viewport
- Report content width via SetCursorPosX+Dummy for the scrollbar
- Use average character width for cols estimate (not "M" width)
The terminal renderer continues using coloffs correctly—no changes
needed there.

KTE_STATIC_LINK defaulted to ON, which fails on systems where ncurses
is only available as a shared library. The Nix build already passed
-DKTE_STATIC_LINK=OFF explicitly; this makes the default match.
Also add add_link_options("-stdlib=libc++") for Clang builds — without
it, compilation uses libc++ but the linker defaults to libstdc++,
causing undefined symbol errors.

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.

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.

Multi-window:
- Per-window ImGui contexts (fixes input, scroll, and rendering isolation)
- Per-instance scroll and mouse state in ImGuiRenderer (no more statics)
- Proper GL context activation during window destruction
- ValidateBufferIndex guards against stale curbuf_ across shared buffers
- Editor methods (CurrentBuffer, SwitchTo, CloseBuffer, etc.) use Buffers()
accessor to respect shared buffer lists
- New windows open with an untitled buffer
- Scratch buffer reuse works in secondary windows
- CMD-w on macOS closes only the focused window
- Deferred new-window creation to avoid mid-frame ImGui context corruption
Swap file cleanup:
- SaveAs prompt handler now calls ResetJournal
- cmd_save_and_quit now calls ResetJournal
- Editor::Reset detaches all buffers before clearing
- Tests for save-and-quit and editor-reset swap cleanup
