feature: WASM execution pipeline, file dispatch, RAM drive, and VFS handle table

- Add file-type dispatch registry (filedispatch.pas) matching files by
  magic header bytes and routing to registered handlers
- Add WASM integration layer: wasmshim, wasmio, wasmrunner, wasmcleanup
  providing full WASI Preview1 bridging (fd_write/read, proc_exit,
  clock, random, args passthrough, environ stubs)
- Add RAM drive (ramdrive.pas) providing in-memory VFS at /disk/ram
  with a built-in hello world WASM binary
- (Placeholder) Implement VFS handle table for proper
  open/read/write/close/filesize routing through registered drives
  and devices
- Integrate file dispatch into vterminal for unknown commands, supporting
  both foreground and background execution of dispatched files
- Expand progmanager init with PS, KILL, TERMINATE, DEV, DISK, MEMRAW,
  BSOD, IFCONFIG, ARP, and TCP commands; wire up ramdrive, filedispatch,
  and wasmrunner initialization
- Replace serial.sendString with syslog.logln in desktop launcher
