CI: harden release and docs workflows

[konard]

Summary

Fixes #11.

• Keep main release runs from being cancelled by follow-up pushes.
• Add explicit timeout-minutes to every release.yml job.
• Update the requested GitHub Actions pins in release.yml and docs.yml.
• Add regression tests for workflow concurrency, job timeouts, and action major versions.

Reproduction

Before the workflow changes, pytest tests/test_workflows.py -q failed because release.yml used literal cancel-in-progress: true, release jobs had no explicit timeouts, and the named actions were still pinned to older major versions.

Verification

• pytest tests/ -v --cov=src --cov-report=xml --cov-report=term
• ruff check .
• ruff format --check .
• mypy src/
• python scripts/check_file_size.py
• pre-commit run check-yaml --files .github/workflows/release.yml .github/workflows/docs.yml

Note: mypy src/ passed, with warnings from the currently installed mypy about the repo's existing python_version = "3.9" config and deprecated --strict-concatenate option.
