feat(apply): Implement CLI command with comprehensive deployment workflow

- Add edge-connect apply command with -f/--file and --dry-run flags
- Integrate config parser, deployment planner, and resource manager
- Provide comprehensive error handling and progress reporting
- Support deployment confirmation prompts and result summaries
- Move internal packages to public SDK packages for CLI access
- Update all tests to pass with new package structure
- Complete Phase 4 CLI Command Implementation
