Add a pre-parse check in quick_validate.py that scans raw frontmatter
text for unquoted description and compatibility values containing
special YAML characters (: # { } [ ]). These characters cause
yaml.safe_load() to silently misparse values into unexpected types
(e.g., dicts instead of strings), making skills fail to load with
no clear error message.
The check runs before yaml.safe_load() and provides an actionable
error message telling the user to wrap their value in quotes.
Fixes anthropics#338
