agent-browser doctor diagnoses and repairs installs

Introduced 2026-04-16 · score 0.95

HOW TO USE IT

When you need to diagnose an agent-browser installation, run `agent-browser doctor` to check the environment, Chrome, daemons, config, security, providers, connectivity, and perform a live headless launch test. Add `--offline`, `--quick`, `--fix`, or `--json` to adjust those checks, opt into repairs, or request structured output.
