This commit updates the license from MIT to the Prosperity Public License 3.0.0.
It also updates the author in the pyproject.toml file to "CoReason, Inc." and adds a contact email.
This commit introduces a new Python package template with a modern, standardized dependency manager (Poetry), a comprehensive, self-validating quality and linting suite using `pre-commit`, an optimized, secure, multi-stage `Dockerfile`, and a robust, secure, and efficient CI/CD pipeline for GitHub Actions.

The template is designed to be fully self-contained and capable of passing its own `pre-commit` checks with zero errors upon creation.

It also includes a dual-licensing model with the Prosperity Public License for non-commercial use and a commercial license available upon request.
This commit re-implements the `lint` job in the `ci.yml` workflow to use a manual setup for `pre-commit`. This change replaces the deprecated `pre-commit/action` with explicit steps to set up Python, cache the `pre-commit` environments, install dependencies, and run the linter.

This change was made to resolve a git authentication error that was causing the CI to fail. The new implementation is more robust and transparent.
This commit adds a step to the `lint` job in the `ci.yml` workflow to configure git to use the `GITHUB_TOKEN` for all HTTPS connections to `github.com`. This is necessary to resolve a git authentication error that was causing `pre-commit` to fail when cloning hook repositories.
This commit corrects the URL for the `hadolint` pre-commit hook in the `.pre-commit-config.yaml` file. The previous URL was incorrect and was causing the CI to fail. The new URL points to a Python-based wrapper for `hadolint`, which should be more reliable in the CI environment.
This commit updates the pre-commit hooks to their latest versions, resolving a warning about deprecated stage names.
This commit introduces a complete, production-ready Python package template with a modern and standardized structure.

Key features include:
- Poetry for dependency management.
- A comprehensive pre-commit suite for code quality, linting, and formatting (Ruff, Mypy, etc.).
- A secure, multi-stage Dockerfile running as a non-root user.
- Robust CI/CD pipelines for GitHub Actions with linting, testing, and Docker image scanning (Trivy).
- All third-party GitHub Actions are pinned to their full commit SHA for security.
- Dual-licensing model with the Prosperity Public License and a commercial option.
This commit resolves the issues identified during the code review to finalize the Python package template.

Key fixes include:
- **Dockerfile Improvement:** The runtime stage of the `Dockerfile` now adds the non-root user's local bin directory to the `PATH` environment variable. This ensures that any command-line scripts installed by dependencies are directly accessible, preventing potential runtime errors.
- **CI Optimization:** The redundant `lint-docker` job has been removed from the `ci.yml` workflow. Dockerfile linting is already handled comprehensively by the `hadolint` hook within the main `lint` job's `pre-commit` execution, making the separate job unnecessary and streamlining the CI process.

This commit introduces a complete, production-ready Python package template.

Features:
- Standardized dependency management using Poetry.
- A comprehensive, self-validating quality and linting suite using pre-commit.
- An optimized, secure, multi-stage Dockerfile that runs as a non-root user.
- Robust CI/CD pipelines for GitHub Actions, including linting, testing across multiple Python versions, and Docker image vulnerability scanning with Trivy.
- All third-party GitHub Actions are pinned to their full commit SHA for enhanced security.
- Includes foundational documentation (README.md, CI_CD_STRATEGY.md, LICENSE).

The generated template passes its own `pre-commit run --all-files` checks, ensuring high-quality, compliant code from the start.
This commit fixes a failure in the CI `test` job where the `setup-python` action would attempt to cache Poetry dependencies before Poetry was installed, leading to a "poetry not found" error.

The following changes have been made to `.github/workflows/ci.yml`:
- Removed the `cache: 'poetry'` option from the `setup-python` action.
- Ensured that Poetry is installed before any caching is attempted.
- Added a step to configure Poetry to create its virtual environment locally within the project (`.venv`).
- Implemented a robust caching mechanism using `actions/cache` to cache the `.venv` directory based on a hash of the `poetry.lock` file.
- Added `--no-interaction --no-root` flags to the `poetry install` command for cleaner execution in a CI environment.
This commit corrects the commit SHA for the `actions/cache` GitHub Action in the `ci.yml` workflow. The previous SHA was invalid, causing the CI pipeline to fail with an "action could not be found" error.

The invalid SHA has been replaced with `0057852bfaa89a56745cba8c7296529d2fc39830`, which corresponds to the latest stable release of `actions/cache` (v4.3.0). This will resolve the CI failure.
