Arch removed the prebuilt broadcom-wl package on 2026-09-02 and rebuilt
broadcom-wl-dkms with replaces=(broadcom-wl). A replaces entry only helps
upgrades of an already-installed package, so the name is now unresolvable
as an explicit pacman target and the ISO offline mirror download fails
with "target not found: broadcom-wl".
broadcom-wl-dkms depends on dkms, so the explicit dkms in the hardware fix
is redundant; linux-headers stays because the module has to build against
the running kernel.
Remove legacy online installer entrypoints, collapse migrations for 4.0, and move setup responsibilities into target-side system, hardware, and user commands.
