Current archiso package does not install initcpio hook files (confirmed:
find /usr -path */initcpio/hooks/archiso returns nothing). Write the hook
and its mkinitcpio install script directly into the profile airootfs so
COPY carries them into the image without any package dependency.
Hook finds ISO by archisosearchuuid= kernel param, waits up to 30s for
the device to appear via blkid, mounts iso9660→squashfs→overlay onto
/new_root. mkinitcpio detects /new_root is already mounted and succeeds.

The releng syslinux.cfg references UI .c32 modules that may not load,
causing syslinux to fall back without archisolabel= in the kernel cmdline
so the archiso initrd hook scans for an empty device label and sets root=''.
- Write our own minimal syslinux.cfg using %INSTALL_DIR%/%ARCHISO_LABEL%
placeholders; Dockerfile now only copies .c32 binaries from releng
- Add squashfs and overlay to mkinitcpio MODULES explicitly
- Remove microcode hook (no intel-ucode/amd-ucode packages installed)

mkinitcpio runs inside the airootfs chroot, so the archiso hook files
(/usr/lib/initcpio/hooks/archiso) must be installed there. Without this
the hook has no device-scanning logic and boots to an empty root mount.

- Disable pacman alpm sandbox in Dockerfile (seccomp blocks it in BuildKit)
- Move mkarchiso from RUN to CMD so it runs with --privileged at docker run time
- Fix output path: mkarchiso now writes to /dist (matches volume mount)
- Add syslinux + imlib2 to Docker build packages and live ISO package list
- Copy syslinux/ and efiboot/ boot configs from archiso releng into profile
- Switch deprecated UEFI grub bootmodes to uefi-x64.systemd-boot
- Fix wrong package names: libpam→pam, light→brightnessctl, remove pkexec
- Set SigLevel=Never and hardcode reliable mirrors in profile pacman.conf
- Add mkinitcpio.conf with archiso hook so initrd can mount the live squashfs
