feat: enhance workflow and testing infrastructure

- Introduced ExecutionMode type for project execution modes (parallel, sequential).
- Updated SetupOpts to use ExecutionMode instead of string literals.
- Enhanced workflow states to include a new "In Review" state with appropriate transitions.
- Implemented TestHarness for end-to-end testing, including command interception and workspace setup.
- Created TestProvider for in-memory issue tracking during tests.
- Refactored project registration and setup tools to utilize ExecutionMode.
- Updated various tools to ensure compatibility with new workflow and execution modes.
- Added new dependencies: cockatiel for resilience and zod for schema validation.
