fix: address 14 PR review comments from coderabbitai/chatgpt-codex

- guards.py: split confirm bypass into explicit check; use .get() for
  dict description to prevent KeyError on missing action keys
- resources.py: use `is not None` for logs stream cache check; add
  on-demand subscribe_once fallback when auto_start is disabled so
  resources return real data instead of a perpetual "connecting" placeholder
- setup.py: always prompt before overwriting credentials even on failed
  probe (transient outage ≠ bad credentials); update elicitation message
- unraid.py: always elicit_reset_confirmation before overwriting creds;
  use asyncio.to_thread() for os.path.realpath() to avoid blocking async
- test_health.py: update test for new always-prompt-on-overwrite behavior;
  add test for declined-reset on failed probe
- test_resources.py: add tests for logs-stream None check, auto_start
  disabled fallback (success and failure), and fallback error recovery
- test-tools.sh: add suite_live() covering cpu/memory/cpu_telemetry/
  notifications_overview/log_tail; include in sequential and parallel runners
- CLAUDE.md: correct unraid_live → live action reference; document that
  setup always prompts before overwriting; note subscribe_once fallback
