Is there a separate pipeline (maybe extra platforms?) we should kick off for this? |

Single-file self-contained binaries for
linux-bionic-arm64/x64(Termux on Android) were silently falling back toapphostinstead ofsinglefilehost, producing non-functional ~11MB binaries instead of the expected ~30MB bundles. Root cause:singlefilehostwas explicitly excluded from the linux-bionic AppHost pack, and CoreCLR was never enabled for linux-bionic builds.Changes
