Pass parsed manifest map to storage adapter

User prompts:
- "pass the parsed map to store_manifest so they dont have to reparse"

Changes:
- Storage adapter callback accepts both manifest (map) and raw_manifest (binary)
- Registry passes both through to the adapter
- Local adapter receives parsed map for future use, writes raw bytes to disk
