Greptile Summary

This PR performs a targeted Next.js downgrade from ^16.2.0 to the exact-pinned 16.1.5 to work around a known crash (Unexpected loadManifest(/.next/server/prefetch-hints.json) call!) when deploying to Cloudflare Workers via @opennextjs/cloudflare@1.17.1. The corresponding bun.lock is fully regenerated to match.

Key changes:

• next version changed from the loose ^16.2.0 range to the exact pin 16.1.5, which correctly prevents any future automatic upgrade that would re-introduce the incompatibility.
• All @next/swc-* platform binaries and @next/env in bun.lock are updated consistently to 16.1.5.
• Minor transitive dependency adjustments (baseline-browser-mapping ^2.9.19 → ^2.8.3, sharp ^0.34.5 → ^0.34.4) reflect what 16.1.5 actually requires and are correct.
• @opennextjs/cloudflare remains at ^1.17.1; once a patched release is published the team intends to re-upgrade Next.js, which will require a deliberate version bump — the exact pin makes that intent clear.

Confidence Score: 5/5

• This PR is safe to merge — it is a minimal, well-scoped dependency pin with no logic changes.
• The change is a single-line version bump in package.json plus the corresponding lock-file regeneration. The root cause (Next.js 16.2.0 / OpenNext incompatibility) is a documented upstream issue; the fix (pin to 16.1.5) is the recommended workaround. No application code is touched, and all lock-file entries are internally consistent. Exact pinning also guards against accidental re-upgrade.
• No files require special attention.
