Scope narrowed: keep existing xtask examples-smoke implementation and wire it into CI/pre-PR checks. Add a CI workflow step (or PR check updates) to run cargo xtask docs-sync --check and cargo xtask examples-smoke; keep cargo xtask examples-smoke --run as manual/scheduled if needed for runtime.
Milestone: v0.5.0 adapter wave
