fix: add missing YAML frontmatter closure in cognitive skills

Fixed YAML parsing errors in 4 skill files that were missing the
closing '---' delimiter in their frontmatter, causing skill loading
failures.

Fixed files:
- skills/auto-superpowers/SKILL.md
- skills/cognitive-context/SKILL.md
- skills/cognitive-planner/SKILL.md
- skills/cognitive-safety/SKILL.md
