Extend CallMatcherIR with positional argument constraints to enable precise matching of function calls by argument position and value. This allows security rules to detect dangerous patterns like socket.bind("0.0.0.0") or chmod(file, 0o777).

This extends argument matching to support positional arguments in addition to keyword arguments. Rules can now validate specific argument values by position index, enabling detection of security issues where dangerous values are passed as positional parameters. The implementation includes proper argument extraction from call sites and supports both numeric literal and complex expression values.
