/**
 * Cached deploy (node_modules/.cache). Skips the convex + wrangler upload when
 * nothing that affects the deployed artifacts changed since the last successful
 * deploy. The digest covers the corpus sources and ingest code (which produce
 * the served `public/corpus/`), the convex functions, the frontend (`src`,
 * `index.html`, the static `public/` assets), and the build/deploy config. The
 * derived `public/corpus/` and the external `public/facsimile/` scans are
 * excluded — the former is captured via its sources, the latter ships to R2 on a
 * separate flow. Set DEPLOY_FORCE=1 to deploy regardless of the cache.
