Issue summary

Sometimes it's very useful to be able to reset the HEAD manually. Lotus supports it.

One use case would be for exporting a snapshot with Forest across upgrades.

E.g.

forest-cli --chain calibnet chain set-head 322351
forest-cli --chain calibnet snapshot export -t 322054 -r 2000

Task summary

  • Add support for RPC-JSON Filecoin.ChainSetHead endpoint
  • Add cli support in chain subcommand

Acceptance Criteria

  • Setting HEAD to a previous epoch works and Forest can revalidate the chain section.
