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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
