Phase 2: Core Memory Access complete

Browse Source 
task 2.9: implement InProcessReader with tests

Add InProcessReader: direct pointer dereference (unsafe) against own
process via Buffer.MemoryCopy. Implements MemoryBase API for in-process
scenarios (injected managed DLL).

8 tests: ImageBase, Read/Write int, ReadBytes, WriteBytes, Read/Write
struct, dispose lifecycle.

All passing: 52 tests (7 Native + 12 MarshalCache + 11 MemoryBase +
8 String + 6 Addressing + 8 InProcessReader).

## 2. Core Memory Access (spec: memory-access)
- [ ] 2.1 Add tests for `MarshalCache<T>`: blittable size, marshal-required flag, IsIntPtr, computed-once behavior
- [ ] 2.2 Implement `WhiteMagic/MarshalCache.cs` to pass 2.1
- [ ] 2.3 Add tests for `MemoryBase` abstract contract + `ExternalReader` round-trip (`Read<T>`/`Write<T>`, arrays) using the current process as target
- [ ] 2.4 Implement `WhiteMagic/MemoryBase.cs` (abstract) and `WhiteMagic/ExternalReader.cs` to pass 2.3
- [ ] 2.5 Add tests for string read/write with encoding, null-terminator stop, and max length
- [ ] 2.6 Implement `ReadString`/`WriteString` on `MemoryBase` to pass 2.5
- [ ] 2.7 Add tests for relative/absolute addressing (`GetAbsolute`/`GetRelative`, `isRelative` flag)
- [ ] 2.8 Implement addressing helpers to pass 2.7
- [ ] 2.9 Add tests + `unsafe` implementation for `InProcessReader` (direct deref against own process); verify shared `MemoryBase` API works for both readers
