Simplify TraceMatrix by removing TestResultEntry and using TestMetrics throughout

[Copilot]

Simplify Trace Matrix Implementation

Implementation Complete ✓

• Remove TestResultEntry class - use TestMetrics directly
• Add helper properties to TestMetrics (Executed, AllPassed)
• Change GetTestResult to return TestMetrics (not nullable)
• Return TestMetrics(0, 0) instead of null for not-found tests
• Update GetAllTestResults to filter out tests with 0 executions
• Update all test files to use new API
• All 117 tests passing
• Update architecture documentation
• Code review completed
• Security check passed
• Quality lint issues fixed
• Use Serializer.Deserialize for automatic format detection

Quality Checks ✓

• ✅ Markdown linting: 0 errors
• ✅ Spell checking: 0 issues
• ✅ YAML linting: 0 errors
• ✅ Build: 0 warnings, 0 errors
• ✅ Tests: 117/117 passing

Final Design

TestMetrics - Single unified type for test metrics:

• Passes - number of passing executions
• Fails - number of failing executions
• Executed - computed property (Passes + Fails)
• AllPassed - computed property (Fails == 0 && Executed > 0)

API Changes:

• GetTestResult(string testName) returns TestMetrics (not nullable)
• Returns TestMetrics(0, 0) if test not found (simpler than null checks)
• GetAllTestResults() returns IReadOnlyDictionary<string, TestMetrics>
• Filters to only include tests with Executed > 0

Test Result Parsing:

• Uses Serializer.Deserialize() from DemaConsulting.TestResults library
• Automatically detects TRX or JUnit format
• Simpler and cleaner than manual try/catch with multiple deserializers

All quality checks passing. Ready for merge.

<issue_title>[Feature]: Simplify Trace Matrix</issue_title>
<issue_description>### Problem Statement

The Trace Matrix logic is a little convoluted.

Proposed Solution

The TraceMatrix needs to provide the following capabilities:

• Export documentation showing for each requirement the test metrics (linked, passed, failed, not-executed)
• Export documentation showing for each test the requirement and metrics (passed, failed)
• Provide the list of unsatisfied requirements

It should satisfy these capabilities in the clearest and most concise way - with a design so obvious that its correct behavior is immediately obvious. Firstly we can recognize some basic facts:

• Every requirement ID is unique
• Any TestOutcome that is not 'IsExecuted' should be ignored
• The combination of TestFileBaseName and TestResult.Name may not be unique because they may come from different TestResult.ClassName, but these duplicate results can be collapsed to a single record counting the passes and fails.

The implementation should therefore be to create a record of TestExecution consisting of:

• FileNameBase (the base name of the test file)
• Name (the test name)
• Passes (number of passes in the file matching the test name)
• Fails (number of fails in the file matching the test name)

For fast access it's possible to assemble a Dictionary[TestName,List[TestExecution]]. This then becomes exceedingly easy to process - a simple FindTestExecutions method given the test name (with or without test source filter) can be:

1. Split into test source and test name
2. Look up the test name in the dictionary
3. Iterate through the list of TestExecution gathering those tests matching the test source

The three core capabilities can be built on top of this core FindTestExecutions functionality.

Alternatives Considered

No response

Usage Examples

Benefits

Exceedingly easy processing, and using a dictionary by test name should improve performance. In almost all projects the number of unique tests is far larger than the number of test files, so the implementation optimizes in the important area.
