docs: add comprehensive pre-implementation checklist and optimization recommendations
Added detailed pre-implementation checklist covering:
- Technical preparation (environment, network, services)
- Performance preparation (baseline metrics, capacity planning)
- Security preparation (access control, security scanning)
- Documentation preparation (runbooks, API docs)
- Testing preparation (test environment, validation scripts)
Added 6 optimization recommendations with priority levels:
1. Master deployment script (High impact, Low effort)
2. Environment-specific configs (High impact, Low effort)
3. Load testing suite (High impact, Medium effort)
4. AITBC CLI tool (Medium impact, High effort)
5. Validation scripts (Medium impact, Medium effort)
6. Monitoring tests (Medium impact, Medium effort)
Includes implementation sequence and recommended priority order.
