Merge feature/sw-ai-template (e27385e) into feature/sw-package (bf16578).
No conflicts; no runtime source, Storybook source or public API change.
Adds the integration record docs/sw/sw-ai-template-integration-2026-10-19.md
and its evidence (Overview 53/53, overlays 19/19, AI consumer 27/27).
The unverified wip/sw-header-composition-unverified branch is not included.
