fix(slides): clarify xml-text-overlap-lint error for positional argument

[BD-ZERO]

Description:

Summary

• When a positional argument is passed instead of --input <path>, the CLI error message now explicitly hints ，need --input, making the required flag obvious instead of a bare "unexpected argument" message.
• Add regression test covering the CLI's stderr/exit-code behavior for this case, and fix an indentation bug in the test file (the new test method and its body were over-indented relative to the surrounding test
  methods).

Test plan

• python3 -m unittest xml_text_overlap_lint_test -v — 53 tests pass

Summary by CodeRabbit

• Bug Fixes

  • Improved command-line error messaging when a positional argument is provided, now advising to use the required --input option.
  • Maintained clear, deterministic failure behavior for invalid CLI usage.

• Tests

  • Added a unit test to verify the CLI exits with code 1, outputs no stdout, and reports the updated “unexpected argument” error with the --input suggestion.
