- PR #63845: fix(agent): raise on failed Copilot ACP prompt turns so quota exhaustion triggers fallback

An issue reports that fallback providers are not triggered when the Copilot monthly quota is exhausted in copilot-acp. Two pull requests propose changes: adding a quota exhaustion pattern to the error classifier's billing classification, and raising an error on Copilot ACP prompt turns that end in failure so fallback can occur.
