fix: restore Package.resolved and add CI retry for HF downloads

- Package.resolved was accidentally deleted when switching to local
  path for fork development. Regenerated with resolved fork commit.

- e2e-test.yml: added 3-attempt retry loop for transient HuggingFace
  API failures (HTTP 500). Set HF_HUB_DOWNLOAD_TIMEOUT=120.

- build.yml: added feature/* branches to trigger CI builds.
