`poetry install` run under pre-commit hook does not apply changes.

Description

pre-commit run poetry-install passed but acted as no-op.

A regular: poetry install noticed the missing package.

Reproduce the Windows 10 case using the shown pyproject.toml and pre-commit configuration, then compare pre-commit run poetry-install with direct poetry install and the active .venv. Confirm the behavior around the poetry-install hook and its environment; done means the missing watermark package is installed and importable afterward.
