Search for Python virtualenv in .venv/

I usually create a virtualenv as a dotfile/dotdir for Python projects, naming it .venv/, which is the standard convention for Pycharm projects. However, I’ve noticed that claude-code searches for virtualenv directories (ex. venv/) within the project directory but doesn’t automatically discover the hidden one.

As a result, it often requires manual prompting to source the virtual environment after each compact. To address this issue, I’ve added an instruction to CLAUDE.md to locate my virtual environment in that directory, but it seems to be largely ignored.

I believe this can be divided into two enhancements:

• Improve Python project virtualenv detection by checking for .venv/ during /init and other relevant times
• If possible, enhance the ability to follow setup instructions from CLAUDE.md about virtualenv more consistently or make it "sticky" (?)
