Register libccd and tg as submodules instead of stray directories

Browse Source 
Both were sitting in deps/ untracked, with dangling .git pointer files into
.git/modules/{libccd,tg} and no .gitmodules entry at all. A clean clone of this
repository got neither, and `git submodule update` had nothing to update. tg's
worktree had also been emptied -- all 95 files staged as deletions inside its
own index -- so the directory held nothing but the pointer.

Both are now real submodules, pinned by SHA and checked against the tag:

  deps/libccd  7931e764a19ef6b21b443376c699bbc9c6d4fba8  = v2.1
  deps/tg      823f78db7e104ad5074288b4f362f0d3ef0fb0b6  = v0.7.9

Named "deps/libccd" and "deps/tg" to match the eight entries already there,
which meant re-registering rather than adopting the existing .git/modules
directories -- those were named "libccd" and "tg" while every other module lives
under .git/modules/deps/. Both checkouts were verified pristine at their tags
first, so nothing was lost by re-cloning.

URLs are https://, which is what both remotes already pointed at. Five of the
existing eight entries use git@github.com:, which a CI checkout with no SSH key
cannot use; that is not this commit's problem and is left alone.

tg is wired into nothing, deliberately, and TODO.md now says so with the reason
it is kept anyway -- indexed point-in-polygon against concave polygons is the
one job GJK and MPR structurally cannot do. That entry is a deadline: either the
consumer appears or the submodule comes out.

Nothing consumes either dependency yet, so the build and the full suite are
unchanged.
