refactor: fix redundant metadata fields across the codebase - Removed VaultMetadata.Name (redundant with directory structure) - Removed SecretMetadata.Name (redundant with Secret.Name field) - Removed AgePublicKey and AgeRecipient from PGPUnlockerMetadata - Removed AgePublicKey from KeychainUnlockerMetadata - Changed PGP and Keychain unlockers to store recipient in pub.txt instead of pub.age - Fixed all tests to reflect these changes - Follows DRY principle and prevents data inconsistency
