7dfd3659ec fix: address code review issues (security, performance, quality) 
Security:
- Add JSON.parse error handling (return 400 instead of 500)
- Add rate limiting fallback when KV unavailable (in-memory Map)
- Add AI prompt injection protection (sanitizeForAIPrompt)

Performance:
- Optimize VPS benchmark matching (O(1) Map lookup vs O(n*m) loop)
- Reduce AI candidates from 50 to 15 (saves ~60% API cost)
- Centralize magic numbers in LIMITS config

Code Quality:
- Remove dead code (unused queryVPSBenchmarks function)
- Extract duplicated region SQL to DEFAULT_REGION_FILTER_SQL
- Replace hardcoded provider IDs with name-based filtering
- Move magic numbers to config.ts LIMITS object

b682abc45d refactor: modularize codebase and add DB workload multiplier 
- Split monolithic index.ts (2370 lines) into modular structure:
  - src/handlers/ for route handlers
  - src/utils.ts for shared utilities
  - src/config.ts for configuration
  - src/types.ts for TypeScript definitions

- Add DB workload multiplier for smarter database resource calculation:
  - Heavy (analytics, logs): 0.3x multiplier
  - Medium-heavy (e-commerce, transactional): 0.5x
  - Medium (API, SaaS): 0.7x
  - Light (blog, portfolio): 1.0x

- Fix tech_specs with realistic vcpu_per_users values (150+ technologies)
- Fix "blog" matching "log" regex bug
- Update documentation to reflect new architecture
