cli: Remove drift detection/fixing feature and database inventory

Remove the drift analyzer and fixer skills, commands, agents, and
supporting library code. The drift detection workflow was not being
actively used and added maintenance overhead without clear value.
Also remove the `--all-databases` flag from the `doctor` command,
which was tied to the drift-related database inventory contract.
The doctor command now focuses on hook and config validation only.
