Align Python version and dependency management across workflows

[Copilot]

The repository had conflicting Python versions and dependency managers across workflows, causing CI failures.

Changes

• sync.yml: Updated to Python 3.13 and uv (was 3.12 with pip)

  • Switched from actions/setup-python@v5 to astral-sh/setup-uv@v3
  • Changed pip install httpx python-dotenv → uv sync --frozen
  • Changed python main.py → uv run python main.py

• README.md: Updated requirement to Python 3.13+ (was 3.12+)

All workflows now match pyproject.toml (requires-python = ">=3.13") and use consistent tooling.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• astral.sh
  • Triggering command: /usr/bin/curl curl -LsSf REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

File	Description
.github/workflows/sync.yml	Updated to use astral-sh/setup-uv@v3 with Python 3.13 and uv commands for dependency installation and script execution
README.md	Updated minimum Python version requirement from 3.12+ to 3.13+ to match pyproject.toml

Review Summary: No issues found. The changes are correct and achieve the stated goal of aligning Python version and dependency management across workflows. All changes are consistent with:

• pyproject.toml (requires-python = ">=3.13")
• .python-version (already set to 3.13)
• .github/workflows/ci.yml (already using setup-uv@v3 with Python 3.13)

The migration from pip install httpx python-dotenv to uv sync --frozen is appropriate as it ensures reproducible builds using the lockfile, and the command changes are syntactically correct.
