feat: Add comprehensive test generation and evaluation commands

- Introduced `/workflow:test-gen` command to automate test workflow generation based on completed implementation tasks, including detailed lifecycle phases, task decomposition, and agent assignment.
- Implemented `/workflow:concept-eval` command for pre-planning evaluation of concepts, assessing feasibility, risks, and optimization recommendations using strategic and technical analysis tools.
- Added `/workflow:docs` command for generating hierarchical architecture and API documentation, with structured task creation and session management.
- Developed `/workflow:status` command to provide on-demand views of workflow state, supporting multiple formats and validation checks for task integrity and relationships.
