Specs Code Cleanup

This is the final cleanup phase of the specs-driven development workflow, designed to run after task review approval. It systematically removes debug logs, temporary comments, and dead code, optimizes imports, and runs formatters like spotless or prettier. The skill is read-only on logic: it won't refactor or fix bugs, just make code production-ready through cosmetic hygiene. It verifies tests still pass, auto-updates the task status to completed, and documents exactly what it cleaned. Works across Java, TypeScript, Python, and others, with language-specific formatter support. Think of it as the final quality gate before you close the ticket.
