Add kSecAttrAccessible attribute to SecItemUpdate call to fix errSecParam (-50) error that occurs on some systems when updating existing Keychain items. Also include OSStatus code in error messages for easier debugging. Fixes altic-dev#135 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
kSecAttrAccessible is a protected attribute that cannot be modified after the Keychain item is created. Attempting to include it in SecItemUpdate causes errSecParam (-50). Only kSecValueData should be passed when updating existing items. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Summary
kSecAttrAccessibleattribute toSecItemUpdatecall to fixerrSecParam(-50) error that occurs on some systems when updating existing Keychain itemsProblem
When updating provider API keys in Keychain,
SecItemUpdatewas called with onlykSecValueDatain the attributes dictionary. On some systems this causeserrSecParam(-50) error because the accessibility attribute is missing.Solution
Pass a properly typed
[String: Any]attributes dictionary that includes bothkSecValueDataandkSecAttrAccessible(consistent with theSecItemAddpath).Fixes #135
