Build me a simple Python tool for web pentesting that takes a target URL and runs a bunch of common checks in one go.

It should detect what the site is running on, look for things like WordPress, Drupal, Apache, or Nginx, try common sensitive paths and files like .git, .env, and backup.sql, brute force a few likely directories like admin, wp admin, and api, and do basic SQL injection checks with simple payloads and error detection. It should also run a few misconfiguration checks and generate some helpful Google dorks automatically.

I want it to print clear results in the terminal and also save a report to a file when I give an output option. Keep it easy to run from the command line with one URL as input. If you need to look up current docs online for anything, go ahead.
