Make failed hemx requests visibly recoverable by updating root-scoped data-hemx-error outlets while preserving fail-closed non-2xx handling and inspectable hemx:error events. The v0 generated-app exemplar now includes a transport error outlet alongside generated field-error targets.

Add generated field-error targets to the v0 add and rename forms so the canonical todo example shows recoverable typed form feedback end to end instead of emitting errors with no visible target.

Add a generated todo notice slot to the v0 normal path so initial render, append, replace, remove, and dynamic Vec<IntoEffect> refreshes visibly compose one reusable TodoRow partial with adjacent generated UI feedback.
req: canonical_authoring/003
Make the canonical v0 todo flow use one TodoRow partial shape for initial list rendering and generated keyed append/replace/remove helpers. Teach hemx-build to treat collection hosts with keyed h-for children as keyed targets, so beginner templates can keep the DRY outer slot + child partial composition.
