Imported ps5-native-app-boilerplate (Makefile, tools, tooling, clean-room runtime builder, CPU demo renderer). The compiler wrapper and build.sh fall back to the host clang when clang-18 is absent (Arch ships clang 22; verified), ccache is optional, and the large home-screen DDS/AT9 assets stay out of git. Identity: PPSA99350 "Steam Remote Play". Submodules pinned: ihslib master 1881b9a, protobuf-c v1.5.2, mbedtls v3.6.4, opus v1.5.2 (the mbedtls/opus revisions ProsperoLight proved on the console). ProsperoLight's sceNet socket adapter, entropy source, mbedtls config and VideoDec2/VideoOut/AGC link stubs are staged under platform/ps5 and vendor/ps5 for M1/M2. Tested: make, make deploy, shsrv launch; the demo screen renders on the TV.
