“Agent is thinking” indicator during processing

On the interview player / live interview screen, there is no clear indication that the agent is “thinking” or processing after the user finishes speaking. I expected a visible thinking/processing indicator so the user knows the system is working.

Steps to Reproduce

1. Go to an active interview session.

2. Answer a question by speaking into the mic.

3. Release the push‑to‑talk key (spacebar) and wait for the agent’s next response.

4. Observe the screen during the delay between your input and the agent’s response.

Actual vs Expected Behavior

Actual: After the user finishes speaking, the UI often appears idle or frozen with no obvious feedback that the agent is processing the input.
Expected: There should be a clear “agent is thinking” indicator (e.g., animated dots, spinner, pulsing icon) to show that the system is receiving/processing and preparing the next question or response.
