- Normalize file content to LF after reading to ensure consistent matching
- Normalize search/replace strings to handle CRLF from model output
- Add comprehensive CRLF normalization tests for both tools
- Consistent with existing edit_file tool behavior
Adds a new search_replace tool that performs a single search and replace
operation on a file, requiring the old_string to uniquely identify the
target text with 3-5 lines of context.
Parameters:
- file_path: Path to file (relative or absolute)
- old_string: Text to find (must be unique in file)
- new_string: Replacement text (must differ from old_string)
