t3hn3rd de6fde05cc feature: preemptive process management - implementation progress 
Implement a preemptive multitasking system for the Asuro kernel.

Context Switching & Scheduling:
- Custom IRQ0 ISR (contextswitcher.pas) with PUSHAD/POPAD ESP-swap
- Round-robin scheduler with priority-based quantum
- Process table using DList of PProcessContext pointers
- Idle process (PID 0) replaces kernel HLT loop

Process Lifecycle:
- create/kill/terminate/sendMessage API (processmanager.pas)
- Process states: Created, Running, Ready, Suspended, Awaiting,
  Finished, Error
- Parent-child tracking (ParentID, smChildExited notification on reap)
- proc_yield, proc_sleep_ms, proc_await, proc_suspend, proc_exit

Resource Binding & Cleanup:
- Per-process resource list
  (bindResource/unbindResource/unbindAllResources)
- TCP sockets auto-bound to owning process (OwnerPID on TTCPSocket)
- socket_cleanup + auto-unbind in DestroySocket

VTerminal Refactor:
- Multi-instance design (heap-allocated TVTermState per terminal)
- Foreground process with incremental stdout/stderr drain via LVGL timer
- Ctrl+C kills foreground process (killForeground)
- Per-terminal CWD, dir stack, FS builtins (CD/LS/PUSHD/POPD)
- Background job support (& suffix, JOBS/FG commands)
- Command history (Up/Down arrow)

Command Consolidation:
- 14 commands extracted from 9 units into centralized progmanager.pas
- Command procedures exported in host unit interfaces
- E1000/TRACER/stdio builtins kept in-place (conditional/circular)

New Units:
- src/include/proctypes.pas — process type definitions
- src/processmanager.pas — core process manager
- src/prog/ping.pas — standalone ICMP ping process
- src/prog/testcmd.pas — test command (proc_sleep_ms demo)
- src/testprocs.pas — process subsystem smoke tests

Misc:
- ICMP callbacks gain userData parameter for concurrency-safe ping
- CLI/STI guards on kalloc/kfree (lmemorymanager.pas)
- LV_KEY_CTRLC constant + Ctrl+C interception in LVGL keyboard hook
- Window owner PID tracking (windows.pas)
- ISR_32 gate override support (isrmanager.pas)
