Subject: [PATCH] feat: scaffold BuildVersion constant for release-please
 marker test

Add x-release-please-start-version marker block in unary/metadata/keepalive
server and client binaries. Register the marker files in extra-files so that
release-please rewrites BuildVersion on each Release PR.

The constant is intended to be referenced from observability code paths
(Cloud Profiler / OpenTelemetry) as service.version metadata.
