kbe 64be4f8275 Fix page-boundary read issue in redirection helper
Risk mitigation:
- redirect now falls back to reading the minimum required bytes (detourLength) if the full buffer (detourLength + 16) cannot be read due to page boundaries.
- First attempt: read detourLength + 16 bytes for the instruction analyzer (preferred).
- Second attempt: read only detourLength bytes if the first attempt fails (bare minimum).
- Throw only if both attempts fail.

This prevents crashes when function interception functions that sit at the very end of a committed page.

Tests: 199 passing, 4 integration/interactive skipped.

kbe 44a368de9c Fix dispatcher crash/deadlock, instruction analyzer, cache equality, task leak, and redirection protection
- MainThreadDispatcher: guard DispatchHook with try/catch so exceptions never escape to native caller; drain and fault pending work on Dispose; synchronize Execute/ExecuteAsync/Dispose against race/dispose.
- InstructionAnalyzer: require ModRM 0xEC for 0x83/0x81 sub-esp/rsp forms, rejecting unsafe RIP-relative or memory forms.
- PatternScannerCache: implement value equality on CacheKey so repeated scans actually hit cache.
- BackgroundTaskExecutor: add remote allocations to the free list immediately after VirtualAllocEx, before any write that could fail and leak.
- redirect: capture and restore original page protection in Apply/Remove instead of leaving target RWX.
- Regression tests for all six fixes.

Tests: 198 passing, 4 integration/interactive skipped.

kbe 3f0bea6bd4 Implement core diagnostic memory layer, execution helpers, and high-level facade slices
Implemented:
- Core: UTF-16 ReadString boundary/alignment fix, target bitness and process id on MemoryBase
- function interception: PatchManager, DetourManager, InstructionAnalyzer, MainThreadDispatcher
- Execution: BackgroundTaskExecutor, InProcessInvoker
- High-level: Magic facade, RemotePointer, async wrappers
- Discovery/external code loading/Window groundwork (PEB/TEB, pattern scanning, raw allocations, DLL external code loading, window/input)

Tests: 180 passing, 4 integration/interactive tests skipped.
