- Check ./chromedriver before system PATH or auto-installer
- Add Docker environment detection and fallback logic
- Provide debug messages for ChromeDriver source identification
- Improve compatibility with undetected_chromedriver in stealth mode
This resolves issues where undetected_chromedriver downloads its own
ChromeDriver version, bypassing mounted binaries in Docker environments.
The project root approach ensures users can manually place the correct
ChromeDriver version and have it reliably detected.
