Description

Route Neuphonic SSE parsing and provider errors through the TTS stream's error event. An SSE response such as data: {"status_code":401,"errors":["invalid API key"]} currently throws directly from the HTTP data listener, outside the stream's task error handling.

Changes Made

• Reject the pending request future on a response parsing error and destroy the request.
• Close the attempt queue on failure and skip flushing it again when the response closes.
• Add provider-rejection and malformed-JSON regressions, plus a patch changeset.

Pre-Review Checklist

• Build passes: Core and Neuphonic plugin build checks run locally.
• AI-generated code reviewed: Focused error handling and regression coverage reviewed; AI-assisted implementation.
• Changes explained: Error propagation and validation described here.
• Scope appropriate: Neuphonic HTTP synthesis error handling, tests and release metadata only.
• Video demo: Not applicable to a provider error-path regression.

Testing

• Both error regressions fail on current main and pass with the change.
• Tests assert no exception escapes the HTTP listener, the TTS error event fires once, output consumption ends, and the request is destroyed.
• Required workspace formatting and lint commands pass (existing lint warnings remain).
• Changeset metadata is validated for @livekit/agents-plugin-neuphonic.
