Add quality standards and team command design patterns documentation

- Introduced a new quality standards document outlining assessment criteria for team command .md files, including completeness, pattern compliance, integration, and consistency dimensions.
- Established quality gates and issue classification for errors, warnings, and informational notes.
- Created a comprehensive team command design patterns document detailing infrastructure and collaboration patterns, including message bus integration, YAML front matter requirements, task lifecycle, five-phase execution structure, and error handling.
- Included a pattern selection guide for collaboration scenarios to enhance team interaction models.
