RUF100 fails to catch `# ruff: noqa`

[ddeepwell]

Summary

Rule RUF100 (unused no-qa) does not catch unused directives when specified as # ruff: noqa or # ruff: noqa: {code}.

See playground for a simplification of the working example of the following three files:

# ruff.toml
[lint]
select = [ "RUF" ]

# example_missed.py
# ruff: noqa

# example_caught.py
# noqa

Execute command: ruff check
