feat: AUR packaging (mcpp-bin + mcpp) + CI auto-publish#170
Merged
Conversation
Add Arch Linux / AUR support modeled on install.sh: - mcpp-bin: prebuilt release binaries (per-arch x86_64/aarch64 tarballs, pinned sha256), the same artifacts install.sh downloads. - mcpp: built from source, self-hosted via mcpp-bin as the bootstrap compiler (mcpp build --target <arch>-linux-musl, like release.yml). Both share one /opt/mcpp + /usr/bin/mcpp wrapper layout. The wrapper pins MCPP_HOME=$HOME/.mcpp and MCPP_VENDORED_XLINGS at the shared bundled xlings, because mcpp resolves MCPP_HOME from the binary's real path (/proc/self/exe) and writes its registry/caches there at runtime — a plain /usr/bin symlink would point that at the root-owned install dir. - scripts/aur/update.sh: bump both packages (refresh checksums + .SRCINFO). - .github/workflows/aur-publish.yml: push both packages to the AUR after the release workflow completes (workflow_run, so per-arch assets exist first). Requires the AUR_SSH_PRIVATE_KEY secret.

update.shidempotent (regenerates byte-identical PKGBUILD/.SRCINFO), fetchesreal release checksums; both packages + the workflow YAML pass syntax/lint.
