Report #70190

[bug\_fix] venv scripts break after the project directory is moved or renamed \(bad interpreter / No such file or directory\)

Recreate the virtual environment in its new location \(\`python -m venv venv\` or \`virtualenv venv\`\) and reinstall dependencies. Do not rely on moving venvs; virtual environments are not relocatable.

Journey Context:
You move a repo from \`~/old/project\` to \`~/new/project\`. Now \`./venv/bin/python --version\` prints \`bad interpreter: /home/you/old/project/venv/bin/python: no such file or directory\`. Inspecting \`venv/bin/pip\` shows a shebang pointing at the old absolute path. You try editing shebangs by hand, but every script and internal path references the old location. The rabbit hole: a venv embeds the absolute path to the base interpreter and writes absolute shebangs in all \`bin/\` scripts. The fix works because recreating the venv rewrites those paths for the new location; virtualenv/venv are intentionally not relocatable.
