fix: correct skill frontmatter and hand-off invocation

Skills need name/description/version frontmatter (not command-style
description/arguments). Updated all 5 skills to proper format with
trigger descriptions.

Fixed dev.md and cms.md hand-offs to use Skill tool invocation
instead of slash command syntax.
