CLI commands for module scaffolding.

This is the SHELL layer in Functional Core / Imperative Shell architecture.
Responsibilities:
- Parse command-line arguments using tools.cli
- Orchestrate scaffolder service calls
- Format output (list files, success/error messages)
- Handle errors and exit codes

Pure functions for generating file content from templates.

Each generator function takes a template context and returns
file content as a string. All functions are pure and deterministic.

Pure template rendering functions for module generation.

This namespace provides pure functions for transforming entity definitions
into code templates. All functions are deterministic and have no side effects.

Scaffolder module port definitions (abstract interfaces).

Scaffolder module schemas for module generation inputs and outputs.

Scaffolder module CLI entrypoint wrapper.

Encapsulates scaffolder-specific CLI startup so that the top-level CLI can
remain as module-agnostic as possible and delegate into this module.

Scaffolder service implementation for module generation.

Orchestrates template rendering and file generation.
