[Broccolito]

Summary

• Remove two Computer Use ZIP pointers whose LFS objects are unavailable, along with their archive metadata and LFS tracking rule.
• Record the omissions in the vendoring script and regenerate its integrity manifest, so a future upstream refresh does not restore the pointers.
• Clarify that these upstream archives are documentation references; no application or native helper source changed.

Verification

• ./scripts/check-vendored-computer-use.sh passed for 391 files.
• cargo fmt --all and ./scripts/clippy-lint.sh passed.
• Version, brand, Copilot naming, cross-build drift, registry, and privacy-registry checks passed.
• The current tree has no Git LFS pointer blobs or filter=lfs attributes.

just check-everything reached its release-mode socket gate after Clippy passed, but that build was stopped when local free disk fell below the repository's 200 GiB floor. UI lint could not complete with this machine's incomplete node_modules (@types/ws is missing). OpenAPI generation was also stopped to preserve disk. Hosted CI can run these gates with a clean checkout and dependencies.

This is a forward fix. Historical commits still contain the two pointer blobs; shared Git history is unchanged.
