Fix API documentation and examples; add comprehensive documentation suite

- Example5: Fix format string bugs (alignment specifier placement, SafeMemoryHandle formatting)
- Example4: Fix DetourManager.Detour() → Create() in all doc strings
- Example3: Fix MemoryBase.CreateFunction() → InProcessInvoker.CreateFunction() in doc strings
- Examples 1-5: Correct all runtime errors and API mismatches vs actual WhiteMagic API
- README: Fix DetourManager.Detour() examples to use Create(); add missing code fence markers
- Add WhiteMagic.Examples project with 5 comprehensive example files (40+ sub-examples)
- Add docfx.json and toc.md for DocFX API reference generation
- Add 5 conceptual guides: architecture, memory-access, execution-models, hooking, troubleshooting
- Ensure zero errors, zero warnings across all projects (net8.0-windows)

Doc strings now teach correct APIs; runtime format bugs eliminated; build succeeds.
