fix: multiple community-reported issues

- feat(plugin.json): add agents declaration to make 9 agents visible
  in /agents command (fixes #66, closes PR #67)

- fix(backend-patterns): correct requirePermission HOF pattern to
  properly wrap handlers instead of expecting Request directly
  (fixes #54, closes PR #63)

- docs(user-CLAUDE): add privacy guideline about redacting secrets
  from logs before sharing (fixes #38, closes PR #39)

- fix(eval-harness): add mandatory frontmatter with name, description,
  and tools fields (closes PR #58)

 ## Personal Preferences
 
+### Privacy
+- Always redact logs; never paste secrets (API keys/tokens/passwords/JWTs)
+- Review output before sharing - remove any sensitive data
+
 ### Code Style
 - No emojis in code, comments, or documentation
 - Prefer immutability - never mutate objects or arrays
