Vishesh 'ironeagle' Bangotra a3c063b569 docs(templates): document CRUD and model CRUD apps and expose them in mkdocs
- Add comprehensive module and function docstrings to crud_app and model_app templates
- Document OpenAPI-first guarantees, non-goals, and usage patterns in templates
- Add template-level __init__.py files with CLI and client usage examples
- Update mkdocs.yml to include CRUD and model-based CRUD template documentation
- Ensure template documentation follows strict package-bound mkdocstrings rules

"""
CRUD route handlers bound via OpenAPI operationId.
This module defines OpenAPI-bound operation handlers for a model-based
CRUD service. Functions in this module are bound to HTTP routes
exclusively via OpenAPI ``operationId`` values.
Handlers explicitly control HTTP response status codes to ensure runtime
behavior matches the OpenAPI contract. Domain models defined using
Pydantic are used for request and response payloads.
No routing decorators, path definitions, or implicit framework behavior
appear in this module. All routing, HTTP methods, and schemas are defined
in the OpenAPI specification.
