/*
 CPasswordStore using QtKeychain.

 Notes:
 - Stores credentials in the system keychain using QtKeychain.
 - Credentials are stored as a small JSON object under a single key per host:
     { "username": "...", "password": "..." }
 - getCredentials() blocks briefly waiting for the keychain response (with a timeout).
   This mirrors the previous synchronous QSettings behavior. In a production app you
   may prefer asynchronous APIs or to move keychain access to a worker thread.
 - Requires QtKeychain to be available and linked into the project.
