Two CI follow-ups to @benbarclay's #30136 salvage:
1. scripts/run_tests_parallel.py — add 'docker' to _SKIP_PARTS so
the new tests/docker/ harness doesn't run in the regular test (N)
matrix. The harness builds the real Dockerfile in a session
fixture, which can exceed pytest-timeout's 180s ceiling on
ubuntu-latest where Docker IS available — it surfaced as 6
identical setup-timeout failures across slices 1–6 on the first
CI run.
The docker harness has its own dedicated runner via
.github/actions/hermes-smoke-test (added in #30136) plus the
docker-lint workflow. Same treatment as tests/integration/ and
tests/e2e/ — runs separately, not in the main shards.
2. hermes_cli/service_manager.py — pin encoding='utf-8' on the
/proc/1/comm read_text call. Ruff PLW1514 enforcement rolled in
between Ben's last push and the salvage; pure ruff-fix, no
behavior change.
