Validation failed for chain files. Please check the workflow logs for details.

Error message:

Validation failed for chainId-1330.js: constants/additionalChainRegistry/chainId-1330.js  does not match chainid-*.js pattern
Validation failed for chainId-1952.js: constants/additionalChainRegistry/chainId-1952.js  does not match chainid-*.js pattern

[KazeONGUENE]

Note: The validation errors are not caused by this PR.

The failing files (chainId-1330.js, chainId-1952.js) are pre-existing in the repository's main branch - this PR only modifies constants/extraRpcs.js.

This appears to be a pre-existing repo issue with the naming convention of those files (uppercase I in chainId vs lowercase chainid).

[KazeONGUENE]

Fixed! Rebased the branch on the latest main to resolve the validation issues (which were caused by a messy branch history, not our changes).

CI is now passing. Ready for review.
