- Added `./hashline` package exports and redirected callers to the new hashline entrypoint. - Moved hashline logic out of `edit/` to `src/hashline` and removed `edit/modes/hashline`/`edit/line-hash` paths. - Added hashline parsers, anchors, types, and diff helpers with stricter input and mismatch validation. - Implemented preflight and cache-recovery execution flows to reapply edits and handle stale anchor mismatches. - Documented the hashline API relocation as breaking changes in `CHANGELOG.md`.
