- Removed `selector`/`sel` arguments from read and grep tool schemas and related execution arg handling. - Reworked read and grep path processing to parse line selectors from `path` suffixes instead of separate fields, including inline range propagation. - Updated delegation and execution call paths (including JS/Python preludes and executor tests) to pass selectors embedded in `path`. - Updated read/grep prompt docs and changelog for the breaking inline-selector API, and removed obsolete selector-specific tests and expectations.
