feat(kernel): implement single-task userspace with ELF64 loader and syscalls

- Add user-accessible page mapping (32-36 MiB) in boot.S with proper permission bits
- Implement ELF64 loader and process management in new process.c module
- Add syscall infrastructure including int 0x80 handler in process-entry.S
- Create userspace programs (sh, ls, cd) with dedicated linker script
- Integrate filesystem path type checking and directory listing functions
- Reserve memory regions for user processes and update kernel memory layout
- Add console input/output support for userspace applications
- Update kernel main loop to start user process after initialization
- Modify Makefile to build and embed userspace ELF images as kernel objects
- Document new userspace capabilities and limitations in README.md
