Feat: add semver and clean up param naming in NitroEnclaveVerifier

[leopoldjoy]

Summary

• Adds ISemver and a version() function (0.1.0) to NitroEnclaveVerifier, consistent with TEEProverRegistry and TEEVerifier
• Removes _ prefix from all function parameters per the convention used in Base's own multiproof contracts (reserved for private symbols like _verifierIdSet); state variable conflicts resolved with new/initial prefixes (e.g. newRootCert, initialMaxTimeDiff) and natural short forms (e.g. submitter, config)

Test plan

• All 64 NitroEnclaveVerifierTest tests pass
