🐛 FIX: Make CLI error assertions resilient to terminal width Typer wraps error messages in Rich panels whose line breaks depend on terminal width. In CI environments with narrow terminals, long assertion substrings get split across lines by box-drawing characters, causing test_analyse_config_negative (and similar) to fail. Add _normalize_output() helper that strips Rich panel formatting and collapses whitespace before substring matching. Applied to test_analyse_config_negative, test_analyse_project_negative, and test_write_rst_negative.

Typer wraps error messages in Rich panels whose line breaks depend

assertion substrings get split across lines by box-drawing characters,
causing test_analyse_config_negative (and similar) to fail.

Add _normalize_output() helper that strips Rich panel formatting
and collapses whitespace before substring matching. Applied to
test_analyse_config_negative, test_analyse_project_negative, and
test_write_rst_negative.
