Package Apple Silicon Wi-Fi defaults as a settings add-on

[maralcbr]

Apple Silicon setup in omacom/omarchy#9835 needs a package-owned NetworkManager default. Add omarchy-settings-asahi, which owns /usr/lib/NetworkManager/conf.d/wifi_backend.conf with wifi.backend=iwd, replacing the runtime installer's generated configuration.

The add-on is aarch64-only, depends on omarchy-settings, networkmanager, and iwd, and is advertised as an optional aarch64 dependency by both settings variants. omarchy-settings-dev provides omarchy-settings. Selection belongs to the Apple image profile and existing Apple migration, so installing settings alone does not impose Apple Wi-Fi defaults on generic ARM or x86 systems. Administrator configuration under /etc retains precedence. Existing 4.0.4 source pins are preserved.

Validation at package commit 097cc7f0adee0adf4cef86494ac2bbfeb70667a5:

• makepkg builds the add-on in an aarch64 container; source checksum and archive ownership/mode verified.
• Native M2 Max makepkg build passes with dependency checks enabled against the installed Omarchy settings provider, NetworkManager and iwd.
• The extracted package is read by NetworkManager's --print-config using isolated configuration directories: the vendor default selects iwd, and a same-name administrator override selects wpa_supplicant. No live network restart was performed.
• Package release version self-tests and 26 upstream-watch tests pass.

This is the package half of a preliminary cross-repository integration. Repository signing/publication and Apple image-profile inclusion must precede distribution of the dependent runtime. This PR does not enable ARM release channels or publish a runtime/image.

Before this can build: omarchy-settings-asahi has pkgver=1, which will never sort against a future release; please give it a real version. The manifest is present. Note this PR also bumps omarchy and omarchy-settings to 4.0.4-2; those are the release pair and their pkgrel is set by the release process, so please drop those two bumps from this PR.

Closing this because it no longer applies. omarchy-settings-asahi Wi-Fi defaults add-on for omarchy#9835, which was closed; build CI failed and it conflicts.

If this is wrong, and it still does something the current branch does not, say so here and it can be reopened.
