Treat `banger`, `bangerd`, and `banger-vsock-agent` as one release by stamping the same version, commit SHA, and build timestamp into every binary through a shared ldflag-backed `internal/buildinfo` package. Add `banger version`, extend daemon ping/status to report the running daemon's build tuple, and keep the guest helper linked to the same build metadata without adding a new public version surface for it. Validate with `GOCACHE=/tmp/banger-gocache go test ./...`, `make build`, `./build/bin/banger version`, and `./build/bin/banger daemon status` after the daemon restarts onto the new binary.
