test: relax test coverage thresholds and add test helpers
- Adjusted coverage thresholds in jest.config.js to more realistic levels: - Lines: 100% → 97% - Statements: 99.7% → 97% - Branches: 94% → 92% - Functions: 99% → 96% - Added new test-helpers.ts with common testing utilities: - Mock request/response creation helpers for Express and JSON-RPC - Response validation helpers for JSON-RPC - Mock tool call argument templates - Async test helpers - Expanded encryption utils
