progress: ImGui Port - Desktop UI + ImGui rendering performance overhaul

Full ImGui desktop environment (desktop.pas):
- Gradient wallpaper, taskbar with clock, start menu
- Desktop icons with click-to-open
- Windowed apps: System Info, Terminal, File Browser, Task Manager
- Terminal dispatches to registered kernel commands with output capture

Performance: Software rasterizer rewrite (imgui.pas, imgbridge.c)
- Quad detection: merge consecutive triangle pairs into fast rect fills
- 3 new fast-path rect fillers (solid/gradient/textured) using REP STOSD
  and 16.16 fixed-point integer inner loops
- Triangle rasterizer rewritten with fixed-point edge functions
- Back-buffer clear: DrawPixel loop -> REP STOSD (~200x faster)
- Render stat debug counters added

ISR-safe input buffering (imgbridge.c)
- Keyboard/mouse events buffered in lock-free ring buffers from ISR context
- Drained once per frame from main loop to prevent data races

Other changes:
- imguitypes.pas: InputTextFlags renumbered for cimgui 1.91+
- video.pas: backBufferLocation getter added
- kernel.pas: VFS init moved earlier, main loop uses desktop_frame,
  mouse hook uses ISR-safe buffering
- lmemorymanager.pas: kalloc/kfree exported with public aliases for C linkage
- scheduler.pas: Root_Task moved to interface for desktop task manager
- terminal.pas: freeParams exposed in interface
