Keep security auditing focused on the base install

Avoid pulling dev-only optional runtimes into the editable pip-audit job, and make the thread-capability guard match the actual concurrency demand of the affected test.

Constraint: pip-audit flagged starlette from the dev editable install, while the lockfile export remains base-install only.
Rejected: global thread skip hook | it masked unrelated test regressions.
Confidence: high
Scope-risk: narrow
Directive: keep security jobs on the distributable surface unless a specific optional extra is under review.
Tested: git diff --check; pytest tests/test_phase5_context_bus.py::TestContextBus::test_parallel_publish_from_threads tests/test_swarm.py::test_swarm_manager_execute_multiple tests/test_managed_runtime.py tests/test_telemetry.py -q
Not-tested: full GitHub Actions run
