feat: Implement workflow phases for test generation and execution

- Added Phase 1: Session Start to detect input mode and create test workflow session.
- Added Phase 2: Test Context Gather to gather test context via coverage analysis or codebase scan.
- Added Phase 3: Test Concept Enhanced to analyze test requirements using Gemini and generate multi-layered test requirements.
- Added Phase 4: Test Task Generate to create test-specific tasks based on analysis results.
- Added Phase 5: Test Cycle Execute to manage iterative test execution and fix cycles with adaptive strategies.
- Introduced BottomPanel component for terminal dashboard with Queue and Inspector tabs.
