The 43-case mock smoke duplicated tests/cli.rs, which already runs the
real binary against fixture providers. Replace the flake's smoke-mock
check with a small packaged-cli check (version JSON, bash completions,
one mock quote), and cut scripts/live-smoke.sh from 672 to ~170 lines:
it now only runs shipped commands against live MSN/Yahoo/IDX and
validates output shape. Rewrite docs/SMOKE.md around the Nix gate and
the drift check.

Run deterministic installer and publisher checks in Nix, align dev and release dependency artifacts, narrow derivation inputs, and use content-aware CI cache keys. Replace duplicate Cargo gates with a Nix pre-push gate; validate JSON streams and cache data in representative packaged-binary smoke cases.
Clear the smoke cache before each cache-group warm case so the following offline and stale-cache checks always start from a fresh baseline instead of earlier group state.
Document the runner behavior in the smoke guide to make the cache-group sequencing explicit.
