Add 16-bit byte-swapped number output

[CtrlLogicDev]

Summary

• Add a 16-bit byte-swapped result for signed INT and unsigned WORD/register values.
• Preserve the existing parsing, explicit bit-length, input-base formatting, and copy conventions.
• Add focused tests and a brief README feature-list entry.

Details

The conversion swaps the two bytes of the resulting 16-bit pattern:

((value & 0x00FF) << 8) | ((value & 0xFF00) >> 8)

Negative values use the application's existing two's-complement semantics. Values outside the signed/unsigned 16-bit range do not receive this result. This intentionally excludes 32-bit word swapping, full byte reversal, and floating-point reinterpretation.

Validation

• dotnet format JPSoftworks.DevNumbers.slnx --no-restore --include src\DevNumbers.Engine\ByteOrderHelper.cs tests\DevNumbers.Test\ByteOrderHelperTest.cs --verbosity minimal
• dotnet build JPSoftworks.DevNumbers.slnx --configuration Debug -p:Platform=x64 --no-restore — succeeded with 0 errors (3 existing nullable warnings)
• dotnet test JPSoftworks.DevNumbers.slnx --configuration Debug -p:Platform=x64 --no-build — 168 passed, 0 failed, 0 skipped
• Manually validated decimal and hexadecimal results in PowerToys Command Palette.
