test(cache): run the remote cache e2e tests against the Cloudflare Worker

[wan9chi]

Motivation

The remote cache e2e cases ran against a Node file backend that imitated a remote cache server's protocol and write policy. #807 → #810 put the test infrastructure in place against that backend: one backend per case, a tap for the request log, blob numbering, corrupt-blob, and a GitHub Actions stand-in. Vite+'s Cloudflare implementation now lives in voidzero-dev/vite-plus-remote-cache-cloudflare, moved there from #718, and the cases can run against it: a real, independently written server for the protocol.

Changes

• Backend. Behind the same remote-cache-server commands, the backend is that Worker at a pinned commit, a git dependency of vite-task-tools, running in workerd through Miniflare:
  • The Worker runs with the compatibility settings, bindings, and limits that wrangler reads from its wrangler.jsonc. Its namespaces are limited to the endpoint's.
  • As in a deployment, every migration is applied with wrangler's SQL splitter, and the namespace is registered for the endpoint and the test repository.
  • The Worker fetches GitHub's key set to verify upload tokens and gets the stand-in's key instead. Any other outbound request fails.
  • corrupt-blob replaces the blob's object in R2 and its recorded size.
• Workspace. The workspace allows esbuild's and workerd's build scripts, which a root pnpm install otherwise rejects. @cloudflare/workers-types provides Miniflare's binding types.
• Removed the file backend and its @fastify/busboy dependency.
• musl. The cases that use the backend are skipped on musl, because workerd's prebuilt binaries require glibc.

None of the snapshots change. The daemon, the tap, the CLI, and the stand-in are untouched. Only the backend behind them is different.

Stacked on #810.

Remote cache staging

Commit: 3454480b913ce6226c6d611040d328e77946cd2a

Cloudflare staging deployment and smoke tests passed. You can now perform manual verification.

Endpoint: https://vp-cache-ci-staging.voidzero-docs.workers.dev/projects/manual

Download the remote-cache-e2e-37270185172-1 artifact from the workflow run. It contains manual-fetch.cbor, manual-manifest.json, and report.json.

PR checks cover public reads and rejected writes. Main-branch push checks also cover authorized HTTP stores. This staging endpoint is shared by all PRs and main. A later deployment replaces its code and manual fixture. Compare the deployment ID in the response with the artifact before manual verification. Closing this PR does not remove staging.

Manual checks and complete e2e plan.
