Adds initial configuration-file support for common architecture rules.

This introduces rules_from_config(...), which loads named architecture rules from a JSON file and returns normal checkable rules that can be used with assert_passes(...) or .check().

The goal is to support simple shared project/team rules while keeping the fluent Python API as the primary and most flexible interface.

Supported rule types in this first slice:

• no_cycles
• forbidden_dependency
• forbidden_external_dependency

Example:

from archunitpython import assert_passes, rules_from_config

def test_configured_architecture_rules():
    for rule in rules_from_config("archunitpython.json"):
        assert_passes(rule)
