- Added markdown prose tests to verify maskNonProse preserves plain prose and masks fenced/tilde blocks.
- Added keyword-in-prose tests that enforced lowercase token matching and ignored code spans, fences, XML, and comments.
- Added highlight-mode tests ensuring only prose keywords are ANSI-highlighted and inline/fenced/XML regions stay unmodified.
- Added workflow/orchestrate assertions that uppercase or path-like forms remain unchanged while lowercase token boundaries are handled correctly.
