- Updated workflow detection in `workflow.ts` to recognize only the lowercase `workflowz` token for detection and highlighting.
- Changed workflow instructions and tips to reference the new `workflowz` trigger for eval fan-out behavior.
- Updated workflow tests to assert `workflowz` matches correctly and previous `workflow`/`workflows` forms no longer trigger.
- 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.
