test(ruvbot): add comprehensive unit tests for security and plugins

- Add 29 AIDefence tests covering prompt injection, jailbreak, PII,
  sanitization, response validation, and performance benchmarks
- Add 24 plugin manager tests covering manifest validation, lifecycle,
  permissions, events, and registry operations
- Fix response validation to detect injection echoes in LLM responses
  by using all injection patterns and adding response-specific patterns
