t3hn3rd 65c62176b0 fix: show live GPU/resolution info in System Information
continuous-integration/drone/push Build is passing
- desktop: Resolution/Graphics fields now read from video frontbuffer
  and gpu.activeDriverName instead of static multiboot/hardcoded values
- gpu: markAvailable sets ActiveName when no driver is active yet, so
  the initial VBE boot driver is reported before any setMode call
- kernel: whitespace cleanup

t3hn3rd 9a1508a88e feature: GPU driver framework with BGA, V86 monitor, and runtime resolution switching
- GPU Framework (gpu.pas): Priority-ordered GPU driver registry with
  mode-change callback system. Drivers register with a priority (lower =
  tried first). After successful setMode, fires registered callbacks in
  order (video → LVGL → desktop) for fully decoupled resolution updates.

- BGA Driver (bga.pas): Bochs Graphics Adapter via drivermanagement PCI
  auto-detection (class=$03 subclass=$00 wildcard). Programs display via
  I/O ports $01CE/$01CF, reads framebuffer from PCI BARs with VMware SVGA
  fallback. Supports arbitrary resolutions (1920x1080, 2560x1440, etc).

- SETRES Command (setres.pas): Runtime resolution switching — just calls
  gpu.setMode; video reinit, LVGL buffer realloc, and desktop relayout
  all fire automatically via GPU mode-change callbacks.

- VESA/VBE: Registered as GPU fallback driver (priority 50), uses V86
  INT 10h for VBE mode switching.

- TSS: Fix SS0 from $08 (code segment) to $10 (data segment); add
  set_esp0/get_esp0 helpers for V86 ring-0 stack management.

- VMM: Add map_page_user() for identity-mapping first 4MB with User bit
  (required for V86 IVT/BDA/video ROM access).

- Desktop: relayout procedure + GPU callback registration for automatic
  dock/watermark repositioning on resolution change.

- V86 Monitor (v86.pas): Full Virtual 8086 mode monitor for executing
  real-mode BIOS interrupts from protected mode. Naked GPF handler with
  instruction emulation (INT, IRET, CLI, STI, PUSHF/POPF, IN/OUT, HLT,
  0x66 prefix for 32-bit variants). Thunk-based entry via IRET into VM86.

- Kernel init order: gpu.init → video.init → vesa.init → bga.init;
  drivermanagement.init moved earlier (before video) so PCI scan detects
  BGA before first use.

# lmemorymanager
Compatibility shim that re-exports the `memory.heap` API under the legacy unit name.
## Overview
The Wasuro WASM VM project references the old unit name `lmemorymanager` for heap memory operations. Because the Wasuro source tree cannot be modified, this shim unit re-exports every public symbol from `memory.heap` so that `uses lmemorymanager` continues to compile without changes. All functions are thin inline wrappers that delegate directly to their `memory.heap` counterparts.
## Dependencies
- `memory.heap` -- the canonical heap allocator implementation in the Asuro kernel.
## Constants
### ALLOC_UNIT
Re-exported from `memory.heap.ALLOC_UNIT`. The base allocation unit size used by the heap allocator.
### DATA_OFFSET
Re-exported from `memory.heap.DATA_OFFSET`. Byte offset from a heap block header to the start of user data.
### PAGE_SIZE_LMM
Re-exported from `memory.heap.PAGE_SIZE_LMM`. Page size used by the lightweight memory manager.
### TOTAL_UNITS
Re-exported from `memory.heap.TOTAL_UNITS`. Total number of allocation units per heap page.
### BITMAP_DWORDS
Re-exported from `memory.heap.BITMAP_DWORDS`. Number of 32-bit words in the per-page allocation bitmap.
### SIZE_PREFIX
Re-exported from `memory.heap.SIZE_PREFIX`. Size of the prefix stored before each allocation to record its length.
### LARGE_ALLOC_MAGIC
Re-exported from `memory.heap.LARGE_ALLOC_MAGIC`. Magic value used to identify large (multi-page) allocations.
## Types
### PHeapPageHeader / THeapPageHeader
Re-exported from `memory.heap`. Pointer and record types describing the header structure at the beginning of each heap page.
## Functions and Procedures
### init
```pascal
procedure init;
```
Initializes the heap memory manager by delegating to `memory.heap.init`.
### kalloc
```pascal
function kalloc(size: uint32): void;
```
Allocates `size` bytes from the kernel heap and returns a pointer to the allocated memory.
### klalloc
```pascal
function klalloc(size: uint32): void;
```
Performs a large kernel allocation of `size` bytes and returns a pointer to the allocated memory.
### klfree
```pascal
procedure klfree(address: uint32);
```
Frees a large allocation previously obtained via `klalloc`.
### kpalloc
```pascal
function kpalloc(address: uint32): void;
```
Allocates a heap page at the specified address and returns a pointer to it.
### kfree
```pascal
procedure kfree(area: void);
```
Frees a standard allocation previously obtained via `kalloc`.
### lmm_total_free
```pascal
function lmm_total_free: uint32;
```
Returns the total number of free bytes available across all heap pages.
### lmm_page_count
```pascal
function lmm_page_count: uint32;
```
Returns the current number of heap pages managed by the allocator.
## Notes
- Every function and procedure in the implementation section is marked `inline`, so the compiler eliminates the wrapper overhead entirely.
- This unit exists solely for backward compatibility with the Wasuro WASM VM build. New kernel code should use `memory.heap` directly.

# types
Empty compatibility shim that satisfies `uses types` references from the Wasuro WASM VM project.
## Overview
Some units in the Wasuro WASM VM source tree include `uses types` to pull in shared type definitions from the Asuro kernel. In the kernel proper, those types may be declared elsewhere or may no longer be needed in the WASM context. This stub unit provides an empty `types` compilation unit so that `uses types` resolves without error during the Wasuro build.
## Dependencies
None.
## Notes
- The unit declares no constants, types, variables, or routines. Its only purpose is to exist as a valid compilation unit.
- If Wasuro code is ever updated to remove the `uses types` dependency, this shim can be deleted.
