Mihawk 4df5c68c11 Scaffold the native pipeline for RetroArch, with the display layer

Sets up this project as the native pipeline's scaffolding plus RetroArch's
sources, so RetroArch is compiled for the title pipeline rather than converted
into it.

- tools/scaffold-native.sh builds the scaffold from
  ../ps5-native-app-boilerplate-main: tooling, runtime (digest verified),
  Makefile and its tools, merged into this repository's tools/ rather than
  replacing them. An earlier version replaced tools/ wholesale and deleted this
  project's own scripts; the copy is now additive and the reason is in the file.
- tools/fetch-retroarch.sh clones the pinned upstream tag into vendor/ and
  records the revision, so "built from RetroArch 1.22.2" is checkable.
- src/display.{hpp,cpp} owns the console's display: VideoOut, direct memory, two
  registered buffers, present-and-wait. The sequence and its two load-bearing
  details come from the sibling application that proved it on hardware.
- src/main.cpp draws a moving bar: the cheapest thing that proves build, title
  format, launcher, VideoOut and the direct-memory path together.
- sce_sys/param.json is this project's identity, PPSA99169.

Evidence: src/display.cpp compiles through the pipeline's compiler
(tooling/prospero-clang18 with PS5_CLANG=/usr/bin/clang, -std=c++20), and a
RetroArch source file compiles the same way with its include paths.

Clean-room runtime shim

libc.prx is generated locally from the independently authored source in this repository and is distributed under GPL-3.0-or-later. It contains no Sony runtime implementation, proprietary SDK binary, or game file.

The release artifact has SHA-256:

e6ff45d16adf687855cc3b33b0c8a4132b6504360b221e0a34c7e99fb3ba0036

Generate it from the repository root:

make libc

Then verify it from this directory with:

sha256sum -c libc.prx.sha256

The generated file is ignored by Git. Bare make also creates it as part of a normal application build. Tagged GitHub Releases provide the verified binary as a convenience asset.

The complete source, reproduction procedure, and compatibility scope are in tooling/native and docs/RUNTIME_SHIM.md.
