syscall_dispatch() - Dispatch a syscall number to grouped subsystem handlers.

src/kernel/syscall.c owns the stable public entrypoints and delegates the large implementation bodies to subsystem-specific pieces:

• syscall_mm.inc : brk/mmap/munmap/clock_gettime
• syscall_fs.inc : VFS, pipes, polling, stat and mount operations
• syscall_proc.inc : fork/exec/wait/signal/session/process helpers
• syscall_net.inc : socket syscalls and lwIP callbacks
