feat: FlowSummary.sample — regenerated stubs

The hub marks bundled sample flows on the wire (field 6, additive);
old hubs decode to false so clients never chip on guesswork.

 ## Unreleased
 
+- Regenerated stubs: `FlowSummary.sample` (wire field 6) — true when
+  a saved flow still carries the bundled-sample header. Old hubs
+  without the field decode to false, so clients can mark and group
+  examples honestly.
+
 - `declareService()` — persist a host service into the operator
   config via the new DeclareService RPC (returns restartRequired).
