fix(ci): include helper binaries in release smoke build

The Linux release workflow needs the sibling helper binaries present before running the headless smoke, otherwise the tagged release job fails before asset packaging starts.

Constraint: Keep the fix scoped to the release workflow so the tag can be rerun without changing runtime behavior
Rejected: Relax the app binary check in smoke mode | release packaging should still verify the real installed binary layout assumptions
Confidence: high
Scope-risk: narrow
Directive: Any release smoke that launches `taskers` directly must build its sibling helper binaries first
