Add process discovery helpers and Magic facade accessors

Introduces ApplicationFinder (by name/title/handle), Magic.Open overloads, and Magic.Threads/Regions/QueryRegion accessors. Closes section 3 of add-thread-region-finder and updates tasks/comparison doc.

 - **`RemoteModule`/`RemoteFunction` follow PE export forwarders** — `kernel32!HeapAlloc` → `NTDLL.RtlAllocateHeap` and similar resolve into the real target module; ordinal and API-set forwarders throw `NotSupportedException` rather than returning a wrong address (task 7.2).
 - **Detour prologue safety is tiered** — the default `StubAssembler` length-decoder covers only the common x86/x64 prologue shapes and refuses any opcode outside that set (zero dependency); the optional `IcedAssembler.GetPrologueLength` decodes arbitrary prologues and is plugged in via `DetourManager.PrologueLengthResolver` when full validation is wanted (tasks 4.6, 8.3).
 - **Iced has no text parser** — the design assumed arbitrary text assembly could be delegated to Iced, but Iced ships only a *fluent* code assembler and a decoder. `IcedAssembler.Assemble` bridges Intel-syntax text onto the fluent API by reflection (registers, immediates, labels; memory operands unsupported), rather than depending on a parser that does not exist (task 8.2).
- **Injection bitness corrections** — the thread-hijack injector enforces matching host/target bitness, so the 32-bit path always runs from a 32-bit caller and uses native `GetThreadContext`/`SetThreadContext`; the WOW64 context APIs (for 64-bit callers inspecting WOW64 targets) never apply here and were removed. `ExternalReader` validates `QueryInformation`/`QueryLimitedInformation` access and surfaces `IsWow64Process` failures instead of silently assuming host bitness.
+- **Thread-control, memory-region, and process-discovery gaps are closed** — this change adds `MemoryBase.QueryRegion`/`EnumerateRegions`/`ChangeProtection`, `RemoteThread`/`ThreadFactory`/`FrozenThread`, and `ApplicationFinder` with `Magic.Open` overloads. WhiteMagic now covers the public surfaces of all four reference libraries.
 - **Bounds and protection hardening** — `AllocatedMemory` range-checks typed IO against region size; `Patch` mirrors the detour's `VirtualProtectEx` dance; `MainThreadPump` guards the completion race on an already-completed `TaskCompletionSource`.
