feat(cli): implement create command with interactive block selection

- Add interactive prompts for project name, block selection, and variant/branch choice
- Support multiple block selection with scoped dependency ordering
- Clone blocks into project structure using git sparse checkout
- Apply Mustache-style template variable substitution
- Compile and merge AI rules (conventions.md, module.yaml) per block
- Integrate with block index, git utilities, and template engine
