Repair theme symlinks the state-move migration left dangling (#6717)

* Repair theme symlinks the state-move migration left dangling

1781043107.sh re-linked legacy theme symlinks whose targets were stored
with a literal "~/.config/omarchy/current/..." string. The replacement
used the same literal tilde, which the filesystem never expands inside a
symlink target, so btop, Helix, and VS Code/Cursor lost their theme and
the migration reported success anyway.

Fix the source migration to relink through the already-defined
$current_state_dir variable, and add a follow-up migration that repairs
the links the applied version left dangling — matching the existing
1785002349.sh pattern, so it is idempotent and leaves custom links alone.

* Only repair theme symlinks that could never have worked

The repair matched any target containing omarchy/current, so a working link
into a user's own dotfiles was rewritten to the state directory and their
setup was lost. Claim a link only when its target starts with a literal "~/",
which the filesystem never expands, and names this exact theme file: that is
what 1781043107.sh wrote, and no working link can look like it. A dangling
target is not enough on its own, since a dotfiles repo may just be unmounted.

* Clean up every scratch directory the CLI suite creates

Five of the eight mktemp directories were never registered with the exit
trap, so each run left them behind in /tmp. Route them all through a helper
that records them for cleanup.

* Drop the theme symlink migration tests

A migration runs once on each machine and is then inert, but a test for it
sits in the suite forever. Now that the repair behaves correctly, keep the
migration and let it go untested rather than grow the suite permanently.
