Replaces the hand-bumped client.Version="0.7.11" with
telemetry.SendForModule which reads the actual module version from
runtime/debug.BuildInfo.Deps at the consumer's build time. This
means future releases (v0.7.12, v0.8.0, …) will be reported by the
running bot WITHOUT requiring a manual edit of client/version.go on
every tag — consumers just `go get -u` and rebuild.
client.Version is preserved as a fallback for replace directives /
detached `go run`, and remains overridable via -ldflags.
Bumps oss-telemetry to v0.2.1.
