fix about lost blockchain state: 2nd PR: implements chain independent update

[dai1975]

In case of optimism-bsc relay, at optimism it takes long time to update headers and then failed in querying to bsc node because it drops old state.
This series of pull-req changes current logic to:

• main logic uses only prove=false query resut
• move SetupHeadersForUpdate and ProveState to later part
• SeupHeadersForUpdate and ProveState runs parallel per chain to avoid lost state because of later SetupHeadersForUpdate chain

I plan this series of pull-req constructs below and this is first part of it.

• fix about lost blockchain state: first pr: add debug prover and debug chain module for testing #174
  • testing base
• this PR
  • handshake connection
  • channel upgrade
  • relay packets

Pull Request Overview

This PR implements chain-independent updates to prevent lost blockchain state issues in relayer operations. The changes refactor the core relay logic to run SetupHeadersForUpdate and ProveState operations in parallel per chain instead of sequentially, addressing the problem where long header update times on one chain cause state queries to fail on another due to dropped old state.

Key changes:

• Parallel processing: Refactors relay operations to use goroutines for concurrent execution per chain direction
• Proof generation restructuring: Moves proof generation logic into separate functions that run concurrently
• Test infrastructure updates: Adds new test scripts and increases timeouts to support the async behavior

@dai1975 Thank you for your great work. Basically OK, but I found some points to fix.
