Report #98766

[tooling] One-off Python scripts still require a manually managed virtualenv and requirements file

Add a PEP 723 inline metadata block \(\`\# /// script\`\) at the top of the script declaring dependencies, then run it with \`uv run script.py\`. uv creates an ephemeral environment, installs the packages, and caches them automatically.

Journey Context:
Agents often do \`python3 -m venv .venv && source .venv/bin/activate && pip install ...\` for a helper that is used once, leaving junk directories behind. \`uv run\` with inline metadata makes the script self-contained: dependencies live in the file, not a separate \`requirements.txt\`, and uv resolves and caches aggressively. If the script is inside a project with \`pyproject.toml\`, remember \`--no-project\` when the script should not inherit project dependencies.
