Use the yaml library (already a project dependency) instead of a
hand-rolled regex to parse and re-serialize frontmatter descriptions,
matching the pattern used in manifest-generator.js. Update tests to
validate round-trip correctness rather than exact quoting style.

The regex that extracts descriptions from YAML frontmatter did not
properly parse quoted values. Descriptions containing apostrophes
(e.g. "can't") produced invalid YAML when re-wrapped in single quotes.
Replace the naive regex with proper handling of single-quoted,
double-quoted, and unquoted YAML values, and escape inner single
quotes using YAML '' syntax before re-wrapping.
Add tests for transformToSkillFormat covering plain, double-quoted,
and single-quoted descriptions with embedded apostrophes.
