Code quality setup

Per-language toolchain

Use the standard toolchain for each language in the repository.

JavaScript / TypeScript (incl. React/Next)

• Format and lint: ESLint + Prettier.
• When configuring Prettier, the agent MUST add and maintain .prettierignore so generated/build outputs and composed files are not formatted/linted as source (e.g., dist/, build artifacts, and AGENTS.md when generated by compose-agentsmd).
• Typecheck: tsc with strict settings for TS projects.
• Dependency scan: osv-scanner. If unsupported, use the package manager's audit tooling.
