ShiftSharp Library

- Claude Sonnet 4.5

Performance Improvements:
Team.cs - Fixed BuildMemberCache() to only build once instead of clearing and rebuilding repeatedly
String concatenation in loops - Converted to StringBuilder in:
Team.ToString()
WorkSchedule.ToString()
Rotation.ToString()
[Multiple files] - Removed inefficient Contains() + Add/Remove patterns that searched lists twice
Bug Fixes:
Team.cs:113-136 - Fixed integer overflow risk in GetDayInRotation() with proper bounds checking
TeamMember.cs:86-94 - Fixed null reference in GetHashCode() for Name property
Named.cs:67-71 - Fixed null reference in GetHashCode() using null-conditional operator
Shift.cs:89-99 - Replaced magic number 500E+06 with named constant NANOSECONDS_ROUNDING_THRESHOLD
Rotation.cs:160 - Changed generic Exception to ArgumentNullException for better exception handling
Code Quality:
[Multiple ToString() methods] - Improved error handling to return partial results instead of empty strings when formatting fails
Shift.cs, Team.cs, WorkSchedule.cs - Added null parameter validation with ArgumentNullException
