Implement hierarchical console output with comprehensive test result display (#1290)

Implement hierarchical console output with comprehensive test result
display

### Modifications:
- Implemented a tree structure using Unicode box-drawing characters (┌─,
├─, ╰─, │) that properly displays the relationship between modules, test
suites, and individual tests with ASCII fallback
- **Test Result Summary**: 
  - Right-aligned duration formatting in consistent `x.xxs` format
- Updated summary format: "X tests completed in Y.ZZs (pass: A, fail: B,
skip: C)"
  - Concise failure summaries in hierarchy for quick scanning
- **Detailed Failure Section**: 
  - Complete hierarchical path display for failed tests
- Comprehensive failure analysis with test count: "FAILED TEST DETAILS
(3)"
  - Detailed expectation failure messages with actual vs expected values
  - Source location information with file and line numbers
  - Progress tracking with error counters [1/3], [2/3], [3/3]
  - Support for multiple expectations per test with individual analysis
- **Unit Tests**: Added automated tests following established patterns
to validate output formatting, hierarchy generation, and failure
handling
