A19: Implement mode checking in access() syscall
- F_OK: check file existence (already done)
- R_OK: assume readable if exists (simplified, no granular perms yet)
- W_OK: check mount read-only flag, return EROFS if read-only
- X_OK: check if file is regular file (FS_FILE), return EACCES if not

Tests: 119/119 PASS (smoke test, SMP=4)
