Goal

Evaluate and migrate the manually deployed MIME and Guix channel configuration to native Guix Home services where doing so removes duplication without weakening channel authentication.

Scope

MIME applications

Replace the tracked ~/.config/mimeapps.list with home-xdg-mime-applications-service-type and home-xdg-mime-applications-configuration, preserving:

added associations;
default applications;
URL-scheme handlers;
the current X11/Wayland image-viewer decision.

Guix channels

Refactor the authenticated channel definitions so the same Scheme data can be consumed by:

guix time-machine -C;
home-channels-service-type for ~/.config/guix/channels.scm;
generation of ~/.config/guix/trusted-channels.scm.

Avoid maintaining two independent lists or allowing %default-channels to override the explicitly pinned/authenticated Guix channel.

Acceptance checks

Generated mimeapps.list is behaviorally equivalent to the current file.
xdg-mime query default returns the expected applications for representative MIME types and URL schemes.
guix pull --dry-run authenticates every configured channel without trust warnings.
guix time-machine -C continues to work from a fresh shell.
The active and trusted channel files contain the intended introductions and pins.
