pub fn store_secret(_key: &str, _value: &str) -> Result<()>Expand description
Store a secret securely in the system keyring.
Platform behavior:
- macOS: Stores in login keychain
- Linux: Stores in Secret Service (GNOME Keyring/KWallet)
- Windows: Stores in Windows Credential Manager
If the secure-storage feature is not enabled or the system doesn’t support keychain, this will return Ok(()) without storing anything.
