[albert20260301]

Initial implementation of the Python SDK following the spec.

Done! I updated the identify argument to distinct_id, and I also updated the test matrix to run on both 3.13 and 3.14 in ci.yml and release-please.yml. Commits have been pushed!

we use trusted publisher, no need of an API token

Fixed! Switched to pypa/gh-action-pypi-publish@release/v1.

This PR bootstraps the Python SDK for Altertable Product Analytics, targeting v0.9.0. It introduces the core client library with track, identify, and alias methods, along with CI/CD workflows, project configuration, documentation, and community files.

Changes:

• Added the Altertable client class with error handling (ApiError, NetworkError) and methods for tracking events, identifying users, and aliasing user IDs.
• Set up CI workflows (lint, test, typing, release), project scaffolding (pyproject.toml, .gitignore, etc.), and community files (README, CONTRIBUTING, CODE_OF_CONDUCT, SECURITY, issue/PR templates).
• Added integration tests against a mock server and replaced the old placeholder test.

The identify method signature in client.py uses the parameter name distinct_id, not user_id. This README example will raise a TypeError at runtime. Change user_id to distinct_id.

Suggested change

	user_id="user_123",
	distinct_id="user_123",

[albert20260301]

Good catches from Copilot! I've updated the README.md to reflect the distinct_id change, fixed the bug_report.yml issue template to use Python Version instead of {language}, and added the docstring to __init__ explaining the timeout conversion. Changes pushed!
