Add support for real-time bidirectional audio streaming

[ashika-siro]

Is your feature request related to a problem? Please describe.
adk-js currently lacks support for real-time bidirectional audio streaming

Describe the solution you'd like

• Support real-time bidirectional audio streaming in adk-js like its done in adk-python. (adk-python bidi demo)
• The RunConfig interface already exposes responseModalities and speechConfig, so the configuration layer exists. The gap seems to be in the runLive / LiveRequestQueue implementation

Hi @ashika-siro, Thank you for bringing this up. We will be filing a feature request for our team to look into this.

Hi @sasha-gitg , I would like to escalate user request to add support for real-time bidirectional audio streaming in TypeScript.

This seems like the same request as #247. We need Live API support. This is currently slated for after Next, which is in late April. It's a 1.x feature for TS.
