Release 1.1.3

fix(ci): pass GITHUB_TOKEN and cache templates for native builds

The native build jobs were failing with 403 on the GitHub Releases API
because packageTemplates re-downloads templates without authentication.

- Upload templates cache from build-and-test as a separate artifact
- Download it in native-build so the script skips the API call entirely
- Pass GITHUB_TOKEN as fallback for workflow_dispatch runs

Eliminates 4 redundant template downloads per release pipeline.
