Refine coding standards and testing guidelines. Updated coderule.mdc to emphasize readability, meaningful comments, and scope discipline. Adjusted testing.mdc to set a 75% coverage threshold for business logic and clarified test data requirements. Enhanced tracker.mdc with a mechanism for handling Jira connection issues and added completeness audit steps in research skills.

 - One assertion per test when practical; name tests descriptively: `MethodName_Scenario_ExpectedResult`
 - Test boundary conditions, error paths, and happy paths
 - Use mocks only for external dependencies; prefer real implementations for internal code

+- Aim for 75%+ coverage on business logic; 100% on critical paths (code paths where a bug would cause data loss, security breaches, financial errors, or system outages — identify from acceptance criteria marked as must-have or from security_approach.md). The 75% threshold is canonical — see `cursor-meta.mdc` Quality Thresholds.
 - Integration tests use real database (Postgres testcontainers or dedicated test DB)
 - Never use Thread Sleep or fixed delays in tests; use polling or async waits
 - Keep test data factories/builders for reusable test setup
