Verified and fixed against real client_portal.dat and client_cell_1.dat files: - Fix header offset: BTree root is at 0x160, not 0x148 (file size field) - Fix BTree entry size: 24 bytes (flags+id+offset+size+timestamp), not 12 - Fix sector-chain node reading: BTree nodes span multiple sectors via linked-list headers; must assemble node data across sector boundaries - Fix DatStreamImpl.Read() BSTR handling: use Buffer.BlockCopy to match C++ SysAllocStringByteLen instead of Marshal.PtrToStringAnsi - Fix DatStreamImpl.ReadBinary() pointer lifetime: inline fixed block to keep destination buffer pinned during Marshal.Copy - Document LoadFilters() dependency on parameterized COM properties in IDecalCore.Configuration that need IDispatch to call correctly Add smoke test project (13/13 tests pass against real DAT files).

Fix DecalDat to work with real AC DAT files

The DAT file reader had several bugs inherited from the old C++ reference
code, which targeted an older format version. Verified and fixed against
real client_portal.dat and client_cell_1.dat files:

- Fix header offset: BTree root is at 0x160, not 0x148 (file size field)
- Fix BTree entry size: 24 bytes (flags+id+offset+size+timestamp), not 12
- Fix sector-chain node reading: BTree nodes span multiple sectors via
  linked-list headers; must assemble node data across sector boundaries
- Fix DatStreamImpl.Read() BSTR handling: use Buffer.BlockCopy to match
  C++ SysAllocStringByteLen instead of Marshal.PtrToStringAnsi
- Fix DatStreamImpl.ReadBinary() pointer lifetime: inline fixed block to
  keep destination buffer pinned during Marshal.Copy
- Document LoadFilters() dependency on parameterized COM properties in
  IDecalCore.Configuration that need IDispatch to call correctly

Add smoke test project (13/13 tests pass against real DAT files).

Initial commit: Complete open-source Decal rebuild

All 5 phases of the open-source Decal rebuild:

Phase 1: 14 decompiled .NET projects (Interop.*, Adapter, FileService, DecalUtil)
Phase 2: 10 native DLLs rewritten as C# COM servers with matching GUIDs
  - DecalDat, DHS, SpellFilter, DecalInput, DecalNet, DecalFilters
  - Decal.Core, DecalControls, DecalRender, D3DService
Phase 3: C++ shims for Inject.DLL (D3D9 hooking) and LauncherHook.DLL
Phase 4: DenAgent WinForms tray application
Phase 5: WiX installer and build script

25 C# projects building with 0 errors.
Native C++ projects require VS 2022 + Windows SDK (x86).
