• Added lib/haven.groovy - library with CLI integration, retry logic, and queue management
• Features:
  • Upload processed media to Haven (Filecoin/IPFS via Synapse)
  • Optional Lit Protocol encryption (havenEncrypt=true)
  • Optional VLM analysis (havenVLM=true)
  • Optional Arkiv metadata sync (havenArkiv=true)
  • Background queue for large files (havenQueue=true)

Unfortunately, we are not adding 3rd party code to our built-in script repository. You're welcome to instruct your users to download your code from your repository and then run it locally via filebot -script /path/to/script.groovy commands though.
