Ignore deps and models as symlinks, not just directories

.gitignore had deps/ and /models/llm/ with trailing slashes. A trailing slash
only matches a real directory, so a *symlink* with the same name is not ignored
and git add -A commits it as a symlink blob.

That bites anyone working in a git worktree, where deps/ and models/ do not
exist and have to be linked in from the main checkout. It already happened once
tonight.
