fix(gen-skill-docs): quote YAML inline scalars containing '...' (Bun strict parser breaks on bare ellipsis)

Browse Source 
A bare ... inside a plain YAML scalar is a document-end marker that strict
YAML parsers (Bun.YAML among them) reject mid-scalar. catalog-trim truncation
appends '...' to any description whose lead exceeds 200 chars, so any
truncated description would generate a SKILL.md with unparseable frontmatter.
Add the ellipsis test to toYamlInlineScalar's needsQuote so such scalars are
emitted double-quoted, plus unit coverage for the quoting rules.
