[Unreleased]

Legacy XOR cipher migration: The enc: prefix (XOR cipher) is now deprecated. Secrets using this format will be automatically migrated to enc2: (ChaCha20-Poly1305 AEAD) when decrypted via decrypt_and_migrate(). A tracing::warn! is emitted when legacy values are encountered. The XOR cipher will be removed in a future release.

SecretStore::decrypt_and_migrate() — Decrypts secrets and returns a migrated enc2: value if the input used the legacy enc: format
SecretStore::needs_migration() — Check if a value uses the legacy enc: format
SecretStore::is_secure_encrypted() — Check if a value uses the secure enc2: format

enc: prefix for encrypted secrets — Use enc2: (ChaCha20-Poly1305) instead. Legacy values are still decrypted for backward compatibility but should be migrated.
