* fix: quote argument-hint YAML values so Copilot CLI ≥1.0.65 loads all skills

`argument-hint: [foo]` YAML-parses as a flow sequence (array), not a
string. Downstream slash-command loaders that validate `argument-hint`
as a string — notably GitHub Copilot CLI ≥ 1.0.65 — silently reject
the skill on load, and the command disappears from the CLI menu.

Wrap the value in double quotes so it parses as a string. No behaviour
change on Claude Code.
