Note

Add Python 3.14 support across CI, install scripts, and runtime, with asyncio policy updates and dependency bumps.

• Build/CI:
  • Add Python 3.14 to matrices in check_wheel_availability.yaml, pre-commit.yml, test-single.yml, and upload-pypi-source.yml.
  • Install scripts updated to detect/allow 3.14 (install.sh, Install.ps1).
• Runtime/Compatibility:
  • Update ChiaPolicy to use asyncio.events._BaseDefaultEventLoopPolicy on Python >=3.14 (chia/server/chia_policy.py).
  • Fix full node long-sync cleanup: only call _finish_sync() if not shutting down (chia/full_node/full_node.py).
  • Use concrete IPv4Address/IPv6Address when storing peers (chia/seeder/dns_server.py).
• Tests:
  • Await ws_server.stop(); improve temp file context; ensure wallet RPC client closed; add consensus mode limit marker; add pytest warning filters.
• Dependencies:
  • Bump bitarray to 3.8.0, markupsafe to 3.0.3, zstd to 1.5.7.2, tach to >=0.32.0; refresh poetry.lock and adjust constraints in pyproject.toml.
