Description
Bug Report
mypy bug.py --disable-error-code=unused-ignore shows
bug.py:1: error: Unused "type: ignore" comment [unused-ignore]
Found 1 error in 1 file (checked 1 source file)
To Reproduce
bug.py
a = 1 # type:ignore[comparison-overlap]
pyproject.toml
[tool.mypy]
enable_error_code = ["unused-ignore"]
Expected Behavior
No error. IMHO, command-line settings should override settings file.
Actual Behavior
See above

- Mypy version used: 1.19.0

Research direction
Reproduce the issue with bug.py, pyproject.toml, and the shown mypy command, then trace mypy's command-line and configuration handling for error-code settings. Done means --disable-error-code=unused-ignore takes precedence over enable_error_code = ["unused-ignore"] and the command reports no error.
