Validation incorrectly flags `ReentrancyGuard` as unsafe in OpenZeppelin v5.5+

Validation fails when using ReentrancyGuard from @openzeppelin/contracts in upgradeable contracts.

Error:

Contract `ReentrancyGuard` has a constructor
Define an initializer instead
https://zpl.in/upgrades/error-001

OpenZeppelin v5.5.0-rc.0 marked ReentrancyGuard as stateless and recommends importing from @openzeppelin/contracts (not -upgradeable):
https://github.com/OpenZeppelin/openzeppelin-contracts/releases/tag/v5.5.0-rc.0

"ReentrancyGuard and ReentrancyGuardTransient are flagged as stateless and are no longer transpiled. Developers must update their imports to use the equivalent version available in @openzeppelin/contracts."

Current workaround:

opts.unsafeAllow = "constructor";

Validator should recognize @custom:stateless contracts from OZ v5.5+ as safe.

Affected contracts:

• ReentrancyGuard
• ReentrancyGuardTransient
• ERC721Holder
• ERC1155Holder

Environment:

• openzeppelin-foundry-upgrades: v0.4.0
• openzeppelin-contracts: v5.5.0

Start with the validator logic that reports constructors as unsafe, then trace how it handles OpenZeppelin contracts and the @custom:stateless annotation. Verify the affected ReentrancyGuard, ReentrancyGuardTransient, ERC721Holder, and ERC1155Holder contracts are accepted without unsafeAllow="constructor", and add or update validation coverage if the project has it.
