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

-    Copy the uuid, in our case `7d395c96-891c-4139-b77d-9b6b144b0b93` and replace the uuid found in `.vscode\launch.json` under `args`, so that it looks something like this:
+    Copy the uuid, in our case `7d395c96-891c-4139-b77d-9b6b144b0b93` & create a `localenv.json` file in the project root with the following content:
     ```json
     {
-        "configurations": [
+        "VirtualBox":{
-            {

-            }
-        ]
     }
     ```
     This will allow VSCode to automatically launch VirtualBox once Asuro has been compiled.
+    
+    You can also enable the serial adapter "COM1" in mode "Raw File", give it a path, and provide this path in the `localenv.json` as follows:
+    ```json
+    {
+        "VirtualBox" : {
+            "MachineName": "<YOUR_UUID_OR_MACHINE_NAME>",
+            "LogLocation": "Fully\\Qualified\\Path\\To\\Your\\Log\\File"
+        }
+    }
+    ```
+    This will allow you to see the console output from Asuro in your host terminal.
 13. Open your project folder in VSCode, use CTRL+SHIFT+B to build & F5 to build + run in VBox.
 14. Congratulations! You can now play with Asuro!
