"""Compatibility shim — the compressor lives in `navi.core.compression`.

Existing imports (`from navi.core.compressor import ContextCompressor`) keep
working; new code should import from `navi.core.compression`.

Note for tests: the moved modules each bind their own `settings` object, so a
monkeypatch belongs on the module that reads it
(`navi.core.compression.partition`, `.summarize`, `.compressor`) — patching
this shim would change nothing.
