Module mutator 

Optional jshift-backed in-place JSON field mutation helpers.

Enabled with the jshift Cargo feature. Not used by the core indexing path; provided for tooling that streams JSONL manifests or agent side-channels without full serde_json re-serialization.

Functions

extract_json_field_slice

Zero-copy extraction of a JSON field slice from raw bytes.

update_json_field_inplace

Mutate a JSON byte buffer in-place using jshift.
