Conversation
This allows shipping Viceroy inside the fastly binary so the common path becomes pure local extraction. No more downloads. The embedded binary lives behind a `viceroy_embed` build tag. Without the tag, fastly builds and behaves exactly as before. On first run the binary is decompressed. It's embedded as ztd-compressed to avoid bloating the binary too much if viceroy is not used - Each per-platform release archive grows by 8-10 MB. We already require klauspost/compress so no new dependencies are required. Extraction failures or version mismatches fall through to the existing download flow untouched, as do --viceroy-path and FASTLY_VICEROY_USE_PATH. The pinned Viceroy version is the contents of pkg/embedded/viceroy/VICEROY_VERSION, currently 0.18.0. Bumping it is a one-line edit followed by a checksums refresh. "make build-embedded" builds a CLI executable with Viceroy embedded.

User Impact
End users get a self-contained
fastlybinary (when built withviceroy_embed) that runsfastly compute serveoffline, with no network round-trip to fetch Viceroy on first use. Default builds are unaffected.Are there any considerations that need to be addressed for release?
Per-platform release archives grow by 8-10 MB when built with the
viceroy_embedtag.No breaking changes; the download path remains the fallback and existing overrides (
--viceroy-path,FASTLY_VICEROY_USE_PATH) continue to work.
