Reasoning

component from path globs (test-coverage); effort from diff stats (20+1 LOC, 3 files); LLM: Adds a pytest mark to skip destructive shutdown commands on localhost, improving local developer experience in the test framework (conftest/ini changes).

If a label is wrong, remove it manually and ping @patty-chow so the rules can be tuned. The bot will not re-label items that already have component labels.
