- Removed `pi-natives` chunk language classifier modules and all core chunk subsystems (kind, state, render, edit, resolve).
- Removed chunk-mode CLI/read/edit entrypoints, including `read` command and chunk mode registration/prompt tooling.
- Removed chunk selectors from `read` and `grep` tools, switching behavior to raw/L-range handling.
- Fixed poll wait parsing to keep defaulting to `30s` when the provided value is empty.
- Added markdown `Row` chunk support by introducing `ChunkKind::Row`, mapping it to tag `"row"`, and emitting row chunks for table rows.
- Updated Go chunk parsing to support method signatures (`func (recv) Name`), prefer method parsing in signatures, and adjust root rules to classify package/import chunks correctly.
- Changed chunk-edit behavior to add read-only `read:true`, replace `write:null` deletes with explicit `delete`, and require one explicit action per entry.
- Added safer chunk-edit execution with region matching, replacement reindentation, table-row append handling, and stricter warnings/errors for boundary and invalid operations.
