Previous attempt (c962d6d) added firmware-linux-nonfree to mkosi.conf,
but the CI bundle was still 63 MB and Tiger Lake wedged on tgl_guc.
Two reasons: (1) firmware-linux-nonfree on bookworm is a thin
metapackage that doesn't include firmware-misc-nonfree, which is where
i915 GuC/HuC blobs actually live; (2) Ubuntu's apt-packaged mkosi is
old enough that Repositories=non-free-firmware shorthand likely isn't
wired through to the debootstrap invocation, so firmware packages
silently miss the bootstrap step entirely.
Changes:
- Enumerate firmware packages explicitly in mkosi.conf (firmware-
misc-nonfree, firmware-iwlwifi, firmware-realtek, firmware-amd-
graphics, firmware-intel-sound, intel/amd64-microcode).
- Ship mkosi.sources.d/debian.sources with explicit deb822 so the
non-free-firmware component is unambiguously available.
- Install mkosi 24.3 via pip in CI instead of apt's older build.
- Pin MODULES=most and COMPRESS=zstd via a tracked initramfs-tools
config under mkosi.extra/.
- Narrow .gitignore so only the generated agent binary is ignored,
not the whole mkosi.extra/ tree.
- New check-initrd Makefile target asserts both size (>=150 MB) and
actual presence of i915/tgl_guc_*.bin inside the built initrd, so
a silent firmware-drop regression fails the build loudly.

Tiger Lake and later Intel iGPUs need i915/tgl_guc_*.bin; without
it the i915 init wedges and floods the console. Same story on most
modern wifi/NIC hardware. Pull firmware-linux-nonfree (metapackage
covering misc-nonfree, iwlwifi, realtek, amd-graphics, …) from the
bookworm non-free-firmware repo — single line fix, ~500MB cost to
the squashfs, worth it for booting arbitrary repaired hosts.

mkosi was failing with "systemd-boot was not found at
usr/lib/systemd/boot/efi" because Bootable=yes expects systemd-boot
installed *inside* the image for EFI boot. This image is only ever
PXE-booted — iPXE loads vmlinuz+initrd from TFTP directly, so the
rootfs itself needs no bootloader.
Switching to Bootable=no drops the EFI-image assembly step; the
linux-image-amd64 postinst still creates /vmlinuz and /initrd.img
symlinks that the top-level Makefile copies into the bundle.
