[Bug] Invalid environment config values cause runtime error instead of validation

Question

**Bug Description**
❯   "env": {
      "CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING": 1,
      "MAX_THINKING_TOKENS": 150000
    },

is this block correct for your environment config

⏺ H.toLowerCase is not a function. (In 'H.toLowerCase()', 'H.toLowerCase' is undefined)

wrong values in claude json config throws an error and stops the loop, nice to have would be an error message saying json schema validation failed - values need to be strings.

**Environment Info**
- Platform: darwin
- Terminal: gh
