Nx Run Tasks

If you're working in an Nx monorepo, this handles the grunt work of running tasks across your workspace. It covers the essentials: single project tasks with `nx run`, bulk operations with `run-many`, and the affected command for running tests only on changed code and its dependents. The skill knows to check your package manager, can filter by project patterns or tags, and understands useful flags like skipping cache or stopping on first failure. Honestly most valuable for the affected workflows in CI, where you want to avoid rebuilding everything when you've only touched one library. It also reminds you to check `nx show project` to see what tasks are actually available, including inferred ones from plugins.
