Upgrade viem to 2.54.0 and remove unused Viem bindings

[DZakh]

Summary

Upgrades viem dependency to 2.54.0 across the codebase and removes unused event log decoding functionality from the Viem bindings module.

Key Changes

• Dependency upgrade: Updated viem from 2.46.2 to 2.54.0 in:

  • packages/envio/package.json
  • scenarios/test_codegen/package.json
  • packages/cli/src/executor/init.rs (template initialization)

• Removed unused Viem bindings (packages/envio/src/bindings/Viem.res):

  • Removed eventLog and decodedEvent type definitions
  • Removed decodeEventLogOrThrow external binding
  • Removed keccak256Bytes, encodePacked, and intToHex external bindings
  • Removed ParseError and UnknownContractName exceptions
  • Removed parseLogOrThrow function

• Removed test file: Deleted scenarios/test_codegen/test/Viem_test.res which tested the removed event log decoding functionality

Implementation Details

The removal of event log decoding functionality suggests this capability is no longer needed or has been replaced by alternative mechanisms. The retained bindings (toHex, keccak256, pad, bigintToHex, stringToHex, boolToHex, bytesToHex, concat) cover the core hex encoding/decoding utilities that remain in use.

📝 Walkthrough

Walkthrough

Upgrades viem to 2.54.0 in two package.json files, pins the exact version in the CLI EVM FeatureExternalCalls init branch, removes the keccak256Bytes, encodePacked, and intToHex external bindings from Viem.res, and deletes the associated Viem_test.res test file.

Changes

viem 2.54.0 upgrade

Layer / File(s)	Summary
Version bumps and CLI pin packages/envio/package.json, scenarios/test_codegen/package.json, packages/cli/src/executor/init.rs	Updates viem from 2.46.2 to 2.54.0 in both package files; changes the CLI EVM FeatureExternalCalls extra dependency pin from ^2.0.0 to the exact 2.54.0.
Remove unused Viem.res bindings and tests packages/envio/src/bindings/Viem.res, scenarios/test_codegen/test/Viem_test.res	Removes keccak256Bytes, encodePacked, and intToHex external bindings from the top-level viem bindings file and deletes the Viem_test.res test suite.

257-257: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Exact pin trades patch/security auto-updates for determinism — confirm this is intended.

Pinning generated projects to exact 2.54.0 (rather than ^2.54.0) means scaffolded indexers won't pick up viem patch/security fixes without a CLI release that bumps this literal. That matches the PR's determinism goal, but couples downstream users' viem security posture to your release cadence. If determinism is the priority, prefer committing a lockfile in the template over freezing the manifest, so security patches remain reachable via npm update.
