Rewrite codex-maintenance.sh to scope CI checks to changed files

CI was running a full eval of every host + package on every push/PR,
which was slow enough to routinely time out the Gitea runner. Default
mode now diffs against a base ref and scopes nixpkgs-fmt/statix/eval to
the files that changed and the hosts/packages they can affect; a change
to flake.nix/flake.lock/variables.nix/modules/common/* (or any other
modules/*.nix outside platforms//build-types, whose blast radius isn't
inferable from the path) falls back to evaluating everything. The old
full sweep moves behind --full-check, which CI never passes; --dry-run
adds build-planning on top of whichever scope is active.

Also trims codex-setup.sh's redundant full host eval loop -- that's
what codex-maintenance.sh is for; setup should just install tooling.
