The comment above ensureGatewayAgent carried both the old and the new
contract on consecutive lines: "a local/null connectionId falls through
to the profile path verbatim", immediately contradicted by "only a null
connectionId falls through, explicit local is a registry identity".
Dropped the stale line.
Same wording above prepareGatewayForAgent in gateway.ts, tightened to
match what the code actually does: registryBackendScopeKey only collapses
to the bare profile key for a null or empty id, so an explicit local id
scopes to conn:local::<profile> and stays on the registry route.
Comments only, no behavior change. tsc --noEmit, eslint and the three
affected suites (43 passed) re-verified.
