CI helpers for setup-host releases

Shared scripts and GitHub Actions so every PSXRecomp title uses one standardized release flow.

Start here: ../GAME_PROJECT_SETUP.md

Workflow template

mkdir -p .github/workflows
cp psxrecomp/docs/ci/templates/setup-release.yml .github/workflows/release.yml
# edit YOUR_* placeholders

Template: templates/setup-release.yml

Tools under `psxrecomp/tools/`

Script	Role
`ci/normalize_version.sh`	Normalize / write `VERSION` + `TAG`
`ci/clear_generated.sh`	Clear `generated/` for setup-host CI
`ci/record_pins.sh`	Log `psxrecomp` / `recomp-ui` / `recomp-net` SHAs
`ci/build_emitters.sh`	Build `psxrecomp-game` + `psxrecomp-bios`
`fetch_toolchain.sh`	Download/unpack cmake-clang-v1 (Windows emitter builds; optional embed)
`stage_setup_sdk.sh`	Emitters, OpenBIOS, optional `toolchain/`, MinGW DLLs
`bundle_mingw_dlls.sh`	Copy imported non-system DLLs next to Windows PEs
`package_setup_host.sh`	Lean setup-host zip (optional `--embed-toolchain`)
`../cmake/toolchain-mingw-w64.cmake`	Linux→Windows MinGW cross toolchain
`../host/psxrecomp_codegen_host.*`	Portable Generate & rebuild host (via CMake helper)
`templates/game.gitignore`	Suggested gitignore for title repos

Also use psxrecomp_add_game_runtime(...) in runtime/runtime.cmake for setup-host / full-game wiring. The CLI (psxrecomp_cli.py) lives in this submodule — there is no separate psxrecomp-sdk/ overlay.

Composite actions

- uses: ./psxrecomp/.github/actions/build-emitters

# Prefer package_setup_host.sh (allow-no-toolchain by default).
# fetch-toolchain + --embed-toolchain only for offline-first packs.
- uses: ./psxrecomp/.github/actions/stage-setup-sdk
  with:
    stage: dist/stage-setup-${{ matrix.artifact }}
    recompiler-build: build-recompiler
    allow-no-toolchain: 'true'
    runtime-bin: /mingw64/bin   # Windows / MSYS2

Title responsibilities

Keep only this in the game repo:

Setup-host CMake flags and exe basename
Thin scripts/package_setup_release.sh wrapping package_setup_host.sh
Zip prefix / display name / disc hint in that wrapper
Release notes / GitHub Release job naming

Release checklist

See ../GAME_PROJECT_SETUP.md.
