ahci: scan all ports; fat: mount first valid FAT32 disk
The kernel previously started only AHCI port 0, so any launch where the
firmware/QEMU put something else on port 0 (e.g. the ESP from an implicit
-drive file=fat:rw:esp) left the real disk unnoticed: 'unsupported sector
size 0' and no mount.
- ahci.rs: enumerate CAP.NP/PI ports, start every port that links up
(empty ports settle at DET=0 and are skipped quickly), keep up to 8
disks, and expose disk_count()/select() for the filesystem
- fat.rs: try each disk in port order and mount the first valid FAT32
volume; non-FAT disks are logged and skipped
- scripts/boot.sh: attach the data disk on ide.0 and the ESP on ide.1
(DISK_IMG env var, default /tmp/disk.img), matching the Makefile
- Verified with the disk on port 0 (Makefile style), port 5 (old-style
command line), and with the ESP on port 0; fsck.fat stays clean
