Refactor read_file and ripgrep tools to implement file reading and searching functionalities. The read_file tool now validates paths within a restricted directory and handles line skipping and reading limits. The ripgrep tool is implemented to perform pattern searches with optional flags for line numbers and case sensitivity, enhancing search capabilities and error handling.
