ci: add GitHub Actions workflow to run Python tests (pytest)

[palanikalyan]

Adds a GitHub Actions workflow to run Python test suites with pytest on push and pull requests. This ensures tests run automatically on GitHub for Python 3.10 and 3.11.

Add cache for pip:

          cache: pip
          # Cache will be restored/updated when any of these files change
          cache-dependency-path: |
            requirements*.txt
            pyproject.toml
            poetry.lock

Hi @sferro998866 and maintainers — thanks for the helpful review. I pushed an update (commit 7ad3f4a) addressing your comments:

Removed references to the non-existent master branch from push and pull_request triggers.
Extended the Python matrix to include 3.12.
Added timeout-minutes: 20 to avoid runaway jobs and set strategy.fail-fast: false so parallel jobs don't abort the matrix on the first failure.
Enabled pip caching (cache: pip) and added cache-dependency-path for requirements*.txt, pyproject.toml, and poetry.lock to speed up dependency installs.
The changes are on palanikalyan/memori4:feat/ci-python-tests (commit 7ad3f4a). If you want the workflow to use a different dependency file (e.g., requirements.txt vs requirements-dev.txt) or additional Python versions, I can adjust it quickly.

Because this originates from a fork, a maintainer will need to approve workflow runs for the Actions to run. Once approved I’ll monitor the workflow and iterate on any failing tests.

@GibsonAI/maintainers — this PR adds a workflow from a fork; could someone please approve the workflow run so CI can execute? Thanks!
