fix(poetry-env): preserve venv in project subdirectories (#13932)

* fix(poetry-env): preserve venv in project subdirectories

Keep the active environment while navigating ordinary project children, but switch when entering a nested Poetry project.

Use a path-component boundary so similarly named sibling projects are not mistaken for subdirectories.

Fixes #12377

* fix(poetry-env): normalize active project root

# Poetry Environment Plugin
This plugin automatically changes poetry environment when you cd into or out of the project directory.
Note: Script looks for pyproject.toml file to determine poetry if its a poetry environment
This plugin automatically activates a Poetry environment when you enter a
directory containing both `pyproject.toml` and `poetry.lock`. It keeps the
environment active in project subdirectories, switches to nested Poetry
projects, and deactivates it when you leave the project tree.
To use it, add `poetry-env` to the plugins array in your zshrc file:
