make pr / make docs fail after recent API merges (ruff RUF043 + Sphinx docstring) #145

Summary

After landing the recent go-parity / polish PRs (#136–#144), a clean checkout of master fails local PR gates:

1. make pr / ruff — tests/test_protocols.py uses a non-raw match= pattern with regex metacharacters (RUF043).
2. make docs / Sphinx -W — multiaddr.utils.from_net_addr docstring has a multi-line Args definition list that Sphinx treats as a warning-as-error.
3. Docs inventory — docs/multiaddr.rst (sphinx-apidoc) does not yet list the new multiaddr.filters module.

Expected

• make pr passes
• make docs / make docs-ci passes with SPHINXOPTS="-W"

Proposed fix

• Use a raw-string regex in the wg negative test (match=r"...")
• Flatten the from_net_addr Args docstring to a single-line description
• Add multiaddr.filters automodule section to docs/multiaddr.rst

Notes

A direct commit previously landed these changes on master without GitHub tox CI (workflow only runs on pull_request and pushes to main / github-actions). This issue tracks landing the same fix via a proper PR so Actions can validate it.
