Ln 740 Quality Setup

This coordinator sets up your entire code quality pipeline after project structure is in place. It detects whether you're working with TypeScript, .NET, or Python, then delegates to three specialized workers that configure linters, pre-commit hooks, and test infrastructure in parallel. The smart part is how it checks for existing configs before doing anything, extending incomplete setups rather than clobbering your work. It won't mark itself done until verification passes, meaning your lint command actually runs, tests execute, and hooks fire on commit. If you're spinning up a new project or retrofitting quality tooling onto an existing one, this handles the tedious coordination of ESLint, Prettier, Ruff, Husky, pytest, and friends so you don't have to remember which config files go where.
