Clean up, update, and upgrade this machine's package managers — Homebrew (formulae + casks), npm globals, and (when present) pipx and uv tools — safely and in parallel. Surveys what's outdated first, runs the safe upgrades, guards against known traps (a tool losing its CLI entrypoint on upgrade, a GUI app's binary shadowing a same-named CLI), and HOLDS session-critical cask updates (the terminal running the session, the VPN) for explicit confirmation. Use when the user says "update packages", "upgrade the machine", "clean up homebrew/npm", "update everything", "package cleanup", or "/update-machine".
