refactor: Parameter validation in "async"/"await" methods should be wrapped

[vbreuss]

This PR refactors async methods to follow the best practice of wrapping parameter validation in a synchronous outer method with an inner async implementation. This pattern ensures that parameter validation (like null checks) happens immediately when the method is called, rather than being deferred until the async state machine starts executing.

Key Changes:

• Async methods are split into synchronous outer methods that perform parameter validation and asynchronous inner implementation methods
• Parameter validation exceptions are thrown synchronously before any async operations begin
• Inner async methods use abbreviated parameter names to avoid closure capture of outer parameters
