Implement dependency resolution between layers

**Summary**: Create a dependency management system that ensures layers are deployed in the correct order based on their interdependencies.

**Acceptance Criteria**:
- [ ] Dependency declaration syntax in layer configuration
- [ ] Topological sorting for deployment order
- [ ] Circular dependency detection and prevention
- [ ] Cross-layer output/input parameter resolution
- [ ] Dependency validation during configuration parsing
- [ ] Clear error messages for dependency issues
