 Linux GPU execution, shared-service packaged speech/Google retrieval and public

+The first complete archive passed all 60 extracted file/permission records and
+both installed-layout self-tests, but at 109314948 bytes it exceeds Gitea's

+It is retained as an unpublished candidate. XZ packaging now uses a 64-MiB
+dictionary (preset 9) to compress duplicate decoder/runtime code across large
+ELF files; client decompression needs roughly 65 MiB. All 21 package tests
+passed after this compression change. No runtime files are removed.
