Ship the aether plugin cache under the name Omarchy 4 asks for

Omarchy 4 generates most theme specs from default/themed/neovim.lua.tpl on
top of aether, pinned as `name = "aether", branch = "v3"`. lazy indexes
specs by url and lets an explicit name rename the merged plugin, so the
bare "bjarneo/aether.nvim" entry here built the cache into lazy/aether.nvim
while every aether-themed install renamed that same plugin to lazy/aether at
runtime -- a directory the package never shipped. Picking one of those themes
on a fresh install cloned aether over the network at first launch and left
the session on tokyonight until nvim was restarted. Six stock Omarchy 4
themes route through the template, plus last-horizon.

Naming the entry to match builds the cache into lazy/aether directly. There
is still only one clone: Omarchy 3.8's hackerman theme depends on the bare
"bjarneo/aether.nvim" url, which merges into the same plugin, so 3.8 keeps
resolving offline as before.

Also keep refs/remotes/origin/HEAD when slimming. It pins no objects, but
lazy.nvim resolves the default branch through it for plugins parked on a
detached HEAD by a version pin -- lazy.nvim, LazyVim and blink.cmp. Without
it get_branch() returns nil and every lockfile write asserts, so :Lazy
install/update/sync died with E5113 on a fresh install, taking out the usual
self-heal path too. Regression from 45ca871.
