Changes

MarmotKit update

Layer / File(s)	Summary
MarmotKit FFI surface Vendored/MarmotKit/MarmotKit.xcframework/macos-arm64/Headers/marmot_uniffiFFI.h	The callback-vtable initializer now accepts a const vtable. The header adds incomplete-setup recovery and reset methods with checksum declarations.
Platform module dependencies Vendored/MarmotKit/MarmotKit.xcframework/macos-arm64/Headers/module.modulemap	The module map declares Darwin and builtin standard C module dependencies.
Build provenance and secure-delete result Vendored/MarmotKit/MARMOT_VERSION, Vendored/MarmotKit/Sources/MarmotKit/MarmotKitVersion.swift, whitenoise-macTests/whitenoise_macTests.swift	Vendored MDK identifiers and public build provenance constants reference the updated build. The secure-delete result sets erasurePending to false.
