The Problem
bunnycurrently blindly Base64-encodes all OCI annotations when writingurunc.json. This makes it impossible foruruncto safely distinguish between intended Base64 payloads and standard plaintext config labels without relying on unsafe heuristics.The Solution
This PR prepends a strict
"b64:"prefix to all encoded annotations generated inhops/package.go.This enables
urunc's new strict parser to safely decode these payloads without the risk of silently corrupting plaintext labels that happen to look like valid base64.context : urunc-dev/urunc#771
