feat: Replace cookiecutter with built-in MiniJinja templating

- Add MiniJinja dependency for Jinja2-compatible templating - Create new project_template.rs module for template rendering - Bundle snowflake template in templates/snowflake/ directory - Remove dependency on external cookiecutter Python tool - Handle Gitea publishing natively in Rust instead of Python hooks - Update default template path to use bundled template with fallback - Update README to reflect new built-in templating - All tests pass Generated by Mistral Vibe.

+"""Post-generation hook: optionally publish the new project to Gitea.
+
+Cookiecutter renders this file as a Jinja template before running it, so a
+doubled opening brace anywhere outside a cookiecutter variable is read as the
+start of a Jinja expression and breaks the render. The JSON body below is
+therefore built with ``json.dumps`` rather than written out with literal braces.
