Pull Request Overview

This PR fixes build-time keychain errors by deferring keyring initialization from package init time to first use through lazy initialization.

• Removed init() function and replaced with ensureKeyringProvider() using sync.Once for thread-safe lazy initialization
• Added calls to ensureKeyringProvider() in GenerateEncryptionKey() and GetEncryptionKey() functions
• Prevents keyring system from being accessed during build/package initialization

Comments suppressed due to low confidence (1)

pkg/utils/encryption.go:1

• The ensureKeyringProvider() call in GetEncryptionKey() lacks test coverage to verify that the keyring provider is properly initialized on first use. Consider adding a test that validates lazy initialization behavior.
