stage-11: security hardening

Browse Source 
- Prompt injection protection: external messages wrapped in [EXTERNAL CONTENT]
  markers, system prompt instructs Claude to never follow external instructions
- Invocation logging: all Claude CLI calls logged with channel, model, duration,
  token counts to echo-core.invoke logger
- Security logging: separate echo-core.security logger for unauthorized access
  attempts (DMs from non-admins, unauthorized admin/owner commands)
- Security log routed to logs/security.log in addition to main log
- Extended echo doctor: Claude CLI functional check, config.json secret scan,
  .gitignore completeness, file permissions, Ollama reachability, bot process
- Subprocess env stripping logged at debug level

373 tests pass (10 new security tests).
