Description

As mentioned in issue #335, the challengeWindow() external view function should be deprecated once challengeWindowSize is made public.

Current Situation

The challengeWindow() function is currently exposed as an external view function in:

• service_contracts/src/FilecoinWarmStorageServiceStateView.sol (line 21-23)

function challengeWindow() external view returns (uint256) {
    return service.challengeWindow();
}

This function retrieves the challenge window size from storage using extsload.

Background

In issue #335, it was decided to make challengeWindowSize public so that tools can fetch this information directly from the contract instead of hard-coding it. Once challengeWindowSize is made public, the challengeWindow() function becomes redundant and should be deprecated.
