Adapt the preflight protection from #128 without its firmware backup or
other installer policy changes. Build a clean private copy against the
running kernel before firmware replacement or DKMS removal. Treat log
initialization failure as an error and add mocked main-flow regressions.

(cherry picked from commit bee40068b9)
Backport the issue #117 loader fix, declaring the 80 firmware/configuration files actually shipped by legacy-mcu1 rather than the main firmware set. Preserve the existing V3 binaries and loader profiles.
All three modules build against Linux 6.17 headers; inventory, built-module metadata and extracted probe error/re-enumeration regression checks pass. Hardware boot validation remains pending.
Document matching kernel headers, pacman dependencies, repository checkout, mode-switch destination creation and MCU1 branch selection. Distinguish missing DKMS builds from stale module indexes and firmware-loader IDs from working interfaces. Correct the installer support claim and explain the NetworkManager connectivity penalty with its upstream reference.
Keeps the contributor-reported Lukton DQ-211 results scoped to that unit. Validation: all Bash examples parse, local links resolve, and commands were checked against the repository installer, Makefile, AUR packaging and upstream documentation. Follow-up corrections for #109; no Arch hardware test is claimed.
(cherry picked from commit 1b071be3e1)
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.
