Fix this error when running op-batcher-tee in current devnet INFO  enclave         > t=2025-09-02T23:12:21+0000 lvl=warn msg="Failed to create a transaction, will retry" service=batcher err="failed to estimate gas: execution reverted, reason: 0x" by building enclave image once in consistent environment, reuse everywhere.

Key places to review:

All changes.
I wrote a script to build PCR0 outside of Docker so it stays persistent. This requires deleting all cached Docker layers. Let me know if you have a cleaner or better solution.

How to test this PR:

(you can also take a look at Readme changes)

docker system prune -f
cd .. && rm -f espresso/shared/*
cd op-batcher && just op-batcher && cd ../espresso
docker compose stop op-batcher-tee
docker compose rm -f op-batcher-tee # make sure any cached PCR0 is deleted
./scripts/build-enclave-image.sh # to build persistent PCR0 outside of docker
COMPOSE_PROFILES=tee docker compose up op-batcher-tee -d

Seems this is due to not building enclave-tools, updated in bd78533

nitro-cli is also needed here, however it's only accessible on x86-64 linux, upd in a08c375.

Close it in favor of #232 and https://app.asana.com/1/1208976916964769/project/1209976130071762/task/1211414707436431. It turns out this is not a PCR0 registration issue. And could be resolved by waiting for 45min at the beginning. Will investigate and try to improve in the new ticket.
