.SYNOPSIS
  Clean Code Pre-Commit & Quality Gate Script.
.DESCRIPTION
  Runs automated verification:
  1. Type checking (TypeScript / tsc)
  2. Linter / Formatter check (Biome / ESLint)
  3. Automated test suite (npm test / vitest / jest)
  4. Static clean code audit (boundary validation, zero secrets, error swallowing)
