[tooling] Installing Python CLI tools globally with pip creates dependency conflicts and stale versions

Run Python tools in isolated temporary environments with \`uvx\` \(alias for \`uv tool run\`\). Example: \`uvx ruff check .\` or \`uvx --with pytest pytest -q\`. Pin a version with \`uvx [email protected]\` and refresh with \`@latest\`. For project-specific commands, use \`uv run\` instead so the project environment is respected.

Journey Context:
Agents often \`pip install --user \`, which pollutes the user environment, breaks when a tool's dependencies conflict with the project, and leaves stale binaries. \`uvx\` creates a cached, disposable virtual environment per tool invocation, pulls the latest version on first use, and does not touch the system or project Python. It is the right default for ad-hoc tools \(linters, formatters, HTTP clients\). The distinction matters: \`uvx pytest\` runs pytest isolated from the project, so for test runners that need the project's packages, prefer \`uv run pytest\`. Use \`--with\` when the tool needs extra plugins in the same ephemeral environment.
