[FEATURE] Visual indicator when Claude is waiting for user input

Problem Statement

Problem
When running multiple Claude Code chats side by side (e.g. parallel feature work across tabs), it's impossible to tell at a glance which chats are mid-flow waiting for my reply vs. which have finished. The chat looks identical in both states, so I have to read through each one to find out.

Proposed Solution

Proposed Solution
Add a visual "waiting for input" state to the chat UI that:

1. Activates when Claude's last message ends the turn and expects a reply (plan approval, gate decision, clarifying question, deploy confirmation, etc.)
2. Shows a distinct visual signal — e.g. a subtle accent border, tab highlight, or background tint on the input area or chat panel
3. Clears automatically as soon as the user types or submits a reply

Use Case
I regularly have 5–7 Claude Code chats open in parallel — each running a different agent workflow. Right now I have to manually check every tab to see which ones are blocked on me. A persistent visual state (even just a colored dot on the tab or a highlighted input bar) would let me triage instantly without interrupting focus.

Alternative Solutions

Alternatives Considered

• Using a text convention like [ YOUR TURN ] at the end of messages — works as a workaround but requires reading each chat, doesn't solve the multi-tab scanning problem
• Terminal bell / notification — too disruptive, doesn't persist until replied
