Cloudflare corpus generator selects no files from WordPress archive

[chubes4]

Problem

npm run generate:cloudflare-wordpress-runtime-corpus completes the archive HEAD request but decodeRemoteZip() yields no selected runtime files for the configured WordPress 7.0.2 archive. The command fails with:

Error: WordPress archive did not yield a runtime corpus.

This blocks npm run cloudflare:local-gate before workerd starts.

Reproduction

1. Check out current main or PR Persist functional WordPress state in Cloudflare #1886.
2. Install dependencies.
3. Run npm run generate:cloudflare-wordpress-runtime-corpus.
4. Observe the zero-file error from scripts/generate-cloudflare-wordpress-runtime-corpus.ts.

Expected

The remote ZIP decoder should enumerate the configured WordPress archive and emit the bounded server corpus, or fail with transport/range diagnostics that explain why no entries were decoded.

Context

The failure reproduced twice against https://downloads.wordpress.org/release/wordpress-7.0.2.zip. Cloudflare runtime contract tests, TypeScript, Wrangler packaging, and a deployed login/editor/publish/public-render workflow all pass independently.

The generator now performs one complete archive download and local decodeZip() selection. CI is green, the real WordPress archive contract reports 4,401 entries / 1,810 selected files / 22,598,313 selected bytes, Wrangler dry-run passes, and the full local Cloudflare gate passes.
