test initialize semantics: typed-overload reverts and re-init protection

[thedavidmeister]

Summary

Pins four initialize invariants on Flow:

1. Flow.initialize(EvaluableConfigV3[]) (the typed overload mandated by ICloneableV2) reverts with ICloneableV2.InitializeSignatureFn on the implementation.
2. Same overload reverts on a successfully initialized clone.
3. _disableInitializers() in the implementation constructor blocks any direct initialize(bytes) call on the implementation.
4. A successfully initialized clone rejects a second initialize(bytes).

OZ Initializable v4 reverts with "Initializable: contract is already initialized".

Mutation verified: removing the initializer modifier from initialize(bytes) makes both re-init tests fail; reverting passes.

Closes #322 #323.

Test plan

• 4 fuzz tests, all 100 runs each
• mutation: drop initializer modifier → re-init tests fail

Warning

Rate limit exceeded

@thedavidmeister has exceeded the limit for the number of commits that can be reviewed per hour. Please wait 54 minutes and 46 seconds before requesting another review.

To keep reviews running without waiting, you can enable usage-based add-on for your organization. This allows additional reviews beyond the hourly cap. Account admins can enable it under billing.

⌛ How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Please see our FAQ for further information.
