Pull #13

github

Fix all 12 build warnings and 6 CodeQL code quality issues

Build warning fixes:
- Fixed XML documentation in DateTimeTypeDecider (removed invalid class-level param tags)
- Added null-forgiving operators (!) in 8 test files for nullable reference warnings

CodeQL code quality improvements:
- Replaced Path.Combine with Path.Join in PackageListIsCorrectTests
- Fixed generic catch clauses with specific exception filters (FormatException, ArgumentException, etc)
- Removed redundant ToString() calls on ReadOnlySpan<char> (use new string() constructor)
- Converted nested foreach/Add patterns to LINQ query expressions in DateTimeTypeDecider
- Changed generic Exception to FormatException in BoolTypeDecider for consistency

All changes improve code quality without affecting functionality.
Build: 0 warnings, 0 errors. Tests: 377/377 passing.
