☂️ Development workflow: EVM verifier

[NickVolynkin]

This is the next stage of template development after #3.

To enable verifying proofs on-chain, circuit developers need to deploy an EVM verifier endpoint based on our EVM verifier and their circuits.

All tasks should include:

• Implementation in the run.sh script, checked in CI
• One-command instructions in the README
• Detailed [manual mode] instructions in the README
