…pansThe three CST xfails in test_offset_encoding now pass; spans match the RST backend (decorators included, trailing newline excluded).
references/referenced_by link each use to its definition (string annotations included), so MatchFinder's reference matching now works on the CST backend.

PythonCstNode(the libcst backend) usable by recipes, as a step towards ADR 11 (libcst for Python, still a Proposal) and the "don't reinvent the wheel" point in #104 and #14. The RST backend stays the default, so existing recipes behave the same.The scope is deliberately minimal: only what is needed in #202 to not duplicate a lot of code, and to be able to actually use what is in the framework
