v0.1.9 - Auth login and API key coexistence

v0.1.9 - Auth login and API key coexistence

This release fixes an important onboarding issue for beginners.

Fixed

• the project no longer implies that Codex, Claude Code, or Gemini CLI must use API keys
• runtime setup now explicitly supports both:
  • API key mode
  • auth/login mode

Improved

• .ai_runtimes.env.example now clearly marks API keys as optional
• configure_ai_runtimes.sh now tells users how to use:
  • openclaw configure or openclaw onboard
  • gemini
  • codex login
  • claude auth login
• health_check.sh now reports empty API env fields as optional instead of warning-level failure

Goal

Make the project friendlier to real-world users, where some tools are authenticated by account login and others by API keys.
