"""Context compression — partition history, summarize it, keep the context in budget.

The implementation is split by responsibility:

* `partition` — pure decisions about what to summarize and what to keep.
* `summarize` — formatting the summarizer prompt, the LLM call, the KEYS line.
* `compressor` — `ContextCompressor`: retry/truncate safety nets and persistence.

`navi.core.compressor` remains as a compatibility shim; new code should import
from here.
