Performance Tuning

Priority: P1 (OPERATIONAL)

Workflow: Performance Audit

1. Switch to Fastify — Replace Express with FastifyAdapter for ~2x throughput.
2. Enable compression — Add Gzip/Brotli middleware.
3. Audit provider scopes — Ensure no unintended REQUEST scope chains.
4. Add query projections — Use select: [] on all repository queries.
5. Profile overhead — Benchmark Total Duration, DB Execution, and API Overhead.
