fix(openclaw): restore SKILL.md frontmatter indentation

Commit 41ec5ca flattened the metadata block while optimizing tokens
across the agent-facing docs, leaving duplicate keys at the same
indent level and failing the YAML parser used by SKILL.test.ts.
Restored the prior nested shape; content text is unchanged.
