feat(runtime): introduce metadata provider layer with full type/member collection

Refactor runtime abstraction and harden stub generation:

- Add IRuntimeMetadataProvider abstraction with Mono/Il2Cpp implementations,
  isolating all native metadata access behind one interface (collected-type
  guarding, field snapshotting at collect time, safe enum-literal reads)
- Fix nested enum emission: enums inside types now generate as real managed
  enums with exact member values (boxed-read chain replaces raw data pointer,
  which returned wrong values on standalone mono)
- Mark operator/conversion overloads (op_*) as specialname so stubs support
  `a + b` / `(int)a` syntax; include return type in operator signature keys
  to keep same-name conversion overloads distinct
- Guard mono_thread_current() probe against SEH on non-attached threads
  (Unity-embedded mono throws instead of returning NULL)
- Add NativeLibraryResolver: per-assembly DllImport resolver funnel with a
  shared ResolveRequested event; redirect Mono P/Invokes through a
  MONO_LIBRARY_NAME placeholder resolved at runtime
- RuntimeManager: detect loaded mono runtimes on Windows (monosgen/bdwgc
  variants) and auto-configure library redirection; route libdl calls
  through Native.DL
- ModLoader: load mod assemblies from bytes so DLLs are not locked on disk
  (regenerating UnmanagedTypeAssembly no longer requires a restart)
- TestDxApp: add TestTypes fixture covering readonly/nested enums/interfaces/
  operators/delegates for stub-generation validation
- version.json: restructure platforms as an array with per-platform
  manager/sha256/entry metadata
- Replace build_release.sh with package_release.sh (zip-only packaging,
  Android bundle no longer ships AAR)
