Add CMFRT naming conventions, object ID ranges, and patterns documentation

- Introduced guidelines for using the "CMFRT" prefix in object names, fields, and procedures to avoid naming collisions and ensure clarity.
- Established rules for object ID ranges to prevent conflicts with other extensions and maintain historical integrity.
- Documented best practices and anti-patterns for various coding patterns, including case statements, interface injection, label usage, and validation methods.
- Implemented a standards review skill to evaluate AL source changes against CMFRT company standards, ensuring compliance with naming, permissions, and architectural patterns.
