📝 Summary

The cache server docs describe behavior that falcondev-oss/github-actions-cache-server#288 replaces: in-bucket merges, AWS SDK credential handling, Nitro env vars and nodejs_* metrics. This updates the pages to describe how the server works after that PR.

Important

Merge only once falcondev-oss/github-actions-cache-server#288 is released.

+  image: ~29 MB static binary on distroless, no shell, probe GET /health over HTTP
~  EAGER_MERGE: object storage streams parts through the server
~  CACHE_CLEANUP_OLDER_THAN_DAYS: a negative value fails startup
-  NITRO_PORT

✅ Verification

• pnpm exec prettier --check packages/gha-cache-server: passes.
• vitepress build for packages/gha-cache-server: build complete.
• Statements checked against refactor/rust-rewrite (src/config.rs, src/storage/object.rs, src/db.rs, src/metrics.rs, src/routes/management.rs, Dockerfile, ADR-0005/0009/0010) and object_store 0.14.2.

💥 Merge danger

Door: two-way

Blast Radius: docs

Merged before the release, the docs describe a server version users can't run yet.
