Implement device filesystem subsystem that provides a VFS interface at /dev for exposing block and character devices. Drivers register devices via devicefs_register_block() or devicefs_register_char(), and the devicefs assigns sequential numbers per device class (e.g., hdd1, hdd2). Features: - Block device ops: read_sectors, write_sectors, sector_size, sector_count - Character device ops: read, write - VFS integration: readdir lists devices, finddir looks up by name - Byte-offset to sector translation for block device reads/writes - Auto-numbering: devices named classN where N starts at 1 per class Also checks off 'ls' task in README.
