ios/: the JIT .aimodel (every iPhone generation specializes it); the h18p AOT files move to ios-h18p/

Measured 2026-09-26 on the iPhone 18 Pro (h19p): an h18p AOT package is refused with incompatibleCompiledAssetArchitecture, while JIT .aimodel bundles up to 1.6 GB specialize on the phone. ios/ now carries the same JIT files as the repository root; the h18p package stays at ios-h18p/ with the other files of ios/. Record: knowledge/jit-distribution.md in john-rocky/coreai-model-zoo.
