…ector Add CLI flag to slither-mutate that filters mutations to specific functions by their selector. Supports both hex selectors (0xa9059cbb) and full signatures (transfer(address,uint256)). Features: - Parse comma-separated selectors with parenthesis-aware splitting - Include modifiers used by target functions - Abort with error if no functions match selector - Combine with --contract-names for precise targeting

Add tests covering all code paths in AbstractMutator.should_mutate_function(): - No filter (target_selectors=None) returns True for all - Matching selector returns True, non-matching returns False - Modifier inclusion when used by target function Also adds onlyOwner modifier and restrictedIncrement() to test fixture.
