Walkthrough
This change adds keyboard events and reusable TUI widgets, updates KC with marking and batch file operations, and extends the Vik editor with Vim-style editing, redo history, and syntax highlighting. It also updates the diagnostics interface, documentation, and host-side and smoke tests.
Changes: TUI and editor updates
Layer / File(s)
Summary
Keyboard event support src/kernel/drivers/keyboard.c, src/kernel/drivers/keyboard.h, src/user/ktuilib.h, docs/TUI_WIDGETS_RU.md
The keyboard driver maps Insert and F1–F10 scan codes to new key values. The TUI key enum adds matching values.
The TUI library adds input, button, checkbox, radio, focus, and list helpers. It adds theme fallback handling and themed rendering for prompts, confirmations, messages, and menus. KTTE adds theme-role mappings and a scrollable role list. Host-side assertions cover widget and theme behavior.
Diagnostics UI integration src/user/diagnostics.c
The diagnostics UI adds mounted-volume status text, uses shared row rendering, maps F1 and F10 to help and quit, and displays a modal widget demo.
KC marking and batch operations src/user/kc.c, docs/TUI_WIDGETS_RU.md
KC adds entry marking and batch copy, move, and delete behavior. It confirms operations, reports results, and clears marks after processing or when the active directory changes.
The editor adds Vim-style motions, operators, visual selections, and registers. Undo and redo use snapshot history. Syntax highlighting is selected by file extension and applied during rendering. Tests cover editor operations and syntax selection.
alexeev-prog/KintsugiOS#4: Adds the earlier keyboard enum entries and TUI APIs that this change extends and uses.
alexeev-prog/KintsugiOS#2: Defines existing TUI helpers used by the updated message, prompt, and confirmation dialogs.
Merge Risk: Low · previous review fd72f
Marks in the file manager can be lost when switching tabs. The editor has a few edge-case problems: some operator-with-G commands give wrong results, d$ on an empty line joins lines, and a no-op redo blocks quitting. None of these is severe, but they are worth fixing soon.

The title "add TUI widgets, improve TUI programs and TUI lib" matches the changeset. The diff adds reusable TUI widgets (input, button, checkbox, radio, list drawing, toggle and focus helpers) in src/user/ktuilib.c and ktuilib.h. It also improves TUI programs such as kc, ktte, kuned, and diagnostics, and it adds Vim-style editing and syntax highlighting. The title names the main change, and it is short and specific. It does not describe every detail, which is expected.

Marks are lost when the user switches between tabs that show different directories.
loaded_directory is stored once per panel, but marks are stored per tab. The [ and ] handlers change p->active. On the next refresh, current->directory differs from p->loaded_directory. The code then clears marks of the tab that was just activated and overwrites loaded_directory. Switching away and back therefore silently discards the marks in both tabs. A T new tab also copies the marks into the new tab.
The marks should be cleared only when that tab's own directory changes. Track the loaded directory per tab.

Do not set dirty when redo does nothing.
history_swap returns early when the redo stack is empty, the undo stack is full, or malloc fails. The caller sets dirty = 1 anyway. Pressing Ctrl+R with no redo history marks an unmodified buffer as modified. :q then fails with "Unsaved changes". The undo path at line 451 has the same pattern, except that it checks undos first.
Return a success flag from history_swap. Set dirty only on success.
Proposed fix
-static void history_swap(char* text, u32* length, u32* cursor, int forward) {+static int history_swap(char* text, u32* length, u32* cursor, int forward) {
Return 0 on each early return; and 1 after free(source[*count]);. Then:

Fix G with a pending operator (dG, yG, d3G).
With op set, the G branch leaves begin = *p and sets end to the start of the target line. It does not swap the two values and does not select whole lines. This causes three failures:
dG from the first line deletes only up to the start of the last line. The last line stays.
A target line before the cursor makes end < begin. vik_yank then computes end - begin + 1 in u32, which wraps. malloc returns null and the operator silently does nothing.
The result is characterwise, not linewise like dj/dk.
Use the same swap and linewise expansion as the j/k branch.
Proposed fix
if (!op) {
*p = end;
return 1;
}
+ if (end < begin) {+ u32 swap = begin;+ begin = end;+ end = swap;+ }+ lines = 1;+ begin = vik_start(t, begin);+ end = vik_end(t, *n, end);+ if (end < *n) {+ ++end;+ }

Do not extend end for d$ on an empty line.
On an empty line, vik_motion with $ returns p == end (the '\n' position). The ++end then includes the newline. d$ or c$ on an empty line joins it with the next line. Vim deletes nothing in this case. Apply ++end for $ only when the line is not empty.
