Install Arch dependencies using the existing package database and explain how to recover from stale package metadata. Avoid errexit on the first firmware count, handle Secure Boot prompt EOF as cancellation, propagate error traps into functions, and reject empty firmware sources before modifying installed firmware.
Validation: eight isolated installer regression tests pass; the original installer fails the affected cases. Bash syntax and ShellCheck error-level checks pass. Fixes#100. Addresses the confirmed findings in #108; other audit suggestions remain separate.
27af5ad added the CFG80211_VERSION make variable for OpenWrt builds that
use a newer mac80211 backport than the target kernel, but it is only
described in a Makefile comment. Document how to pass it from an OpenWrt
package Makefile, link the notes from the installation steps, and add
the build script and the kernel/backports combinations verified for
issue #94.
