publish-runtime.yml had a broad smoke (AgentCard call-shape, well-known
mount alignment, new_text_message) inline as a heredoc. runtime-prbuild-
compat.yml had a narrow inline smoke (just `from main import main_sync`).
Result: a PR could introduce SDK shape regressions that pass at PR time
and only fail at publish time, post-merge.
Extract the broad smoke into scripts/wheel_smoke.py and invoke it from
both workflows. PR-time gate now matches publish-time gate — same script,
same assertions. Eliminates the drift hazard of two heredocs that have
to be kept in lockstep manually.
Verified locally:
* Built wheel from workspace/ source, installed in venv, ran smoke → pass
* Simulated AgentCard kwarg-rename regression → smoke catches it as
`ValueError: Protocol message AgentCard has no "supported_interfaces"
field` (the exact failure mode of #2179 / supported_protocols incident)
Path filter for runtime-prbuild-compat extended to include
scripts/wheel_smoke.py so smoke-only edits get PR-validated. publish-
runtime path filter intentionally NOT extended — smoke-only edits should
not auto-trigger a PyPI version bump.
Subset of #131 (the broader "invoke main() against stub config" goal
remains pending — main() needs a config dir + stub platform server).
