5a6f781c3e fix(emacs-tree-sitter-move): get named parents & check for nils
If there was no parent, the while loop would try to get the parent of
a `nil`, which crashes and burns.

We now also ignore any non-named parents; this might be unnecessary,
if tree-sitter parent nodes are always named, but I don’t know that at
the moment and it’s not documented very well, so better safe than
sorry.

e07e88d81d feat(emacs-tree-sitter-move): left and up movements, skip unnamed
We skip intermediate nodes that do not have any siblings, because they
are irrelevant to navigation and just add extra keypresses without any
highlight changes. This might not be the best choice, we’ll see.

9da760fba4 feat(emacs-tree-sitter-move): Add tree-sitter-move-reset
Resets the cursor to the named node under the cursor.
`-right` does not do it anymore, so it’s possible to navigate on
higher levels of the tree instead of always resetting to a leaf.

806c281b34 feat(users/Profpatsch): moving around via the tree-sitter parse tree
Has a little setup to get the cursor position and map it onto a tree
sitter node. The current node is saved in a cursor variable, and a
highlight overlay marks the range of the current node in the buffer.
