Voice dialog with Superagent (hands-free)

I'd love to have a real voice conversation with my Superagent — not just voice-to-text dictation, but an actual back-and-forth dialog.

Use case: I'm often in the car, between meetings, or on the go. I want to press a button (or use a voice trigger), talk to my agent, get a spoken response, and continue the conversation hands-free until I say something like "goodbye" to end it.

Think of it like Siri — but connected to my personal agent with full memory and context.

Minimum viable: text-to-speech on agent responses. Dream version: full duplex voice dialog.

This would make the Superagent genuinely useful as a daily companion, not just a desktop tool.
