AgentCore Harness Review

Verdict: Looks good

Small, focused refactor that swaps NameStep's hand-rolled TextInput + error state for the shared FormTextInput, matching what HarnessWizard, project create, and memory record list already do. Behavior is preserved (escape → back, Enter only advances when the pattern matches, help text/error rendered by FormTextInput), and the added test assertion (│❯ production) confirms the bordered input renders with the placeholder.

One minor UX shift worth noting (not blocking): pressing Enter on an empty/invalid name is now a silent no-op instead of surfacing the error text, since FormTextInput only renders the error once value !== "". This matches the established pattern in HarnessWizard, so it's consistent.

No new telemetry needed — this is a UI-only refactor of an existing flow. Nothing to change before merge.
