[FEATURE]: Add status light indicator for opencode state

Feature hasn't been suggested before.

I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

When using opencode in a terminal (especially in WSL or tiled window managers), there is no quick way to glance at the terminal title and know whether opencode is idle, thinking, or actively working. Similarly in Web UI, there is no visual indicator on session tabs showing the current state.

Proposal: Add a configurable status light indicator in the terminal title bar and Web UI session tabs:

Color	State
🟢 Green	Idle, waiting for user input, or pending permission/question
🟡 Yellow	Thinking (no active tool or text output)
🔴 Red	Running tools or LLM is generating text

Configuration: status_light: boolean at top-level config, defaults to false.

{ "status_light": true }

In TUI, the indicator is prepended to the terminal title (e.g. 🟢 OC | My Session). In Web UI, a colored dot is shown before the tab title text.

Core logic lives in a shared computeStatusLight() function in packages/core/src/session/status-light.ts, used by both TUI and Web UI.

This issue might be a duplicate of existing issues. Please check:

[FEATURE]: Show a green indicator on project icons when a session is active #23549: Show a green indicator on project icons when a session is active — overlapping concept of visual session state indicators
[FEATURE]: Show pending review indicator for sessions needing attention #27772: Show pending review indicator for sessions needing attention — similar idea of color-coded session state dots in the UI

If your request is distinct from these, please add a note explaining what makes it different.

These are related but distinct:

[FEATURE]: Show a green indicator on project icons when a session is active #23549 is about a green indicator on project icons to show which project has an active session. This PR is about the session's real-time working state (idle/thinking/running) with 3 colors, shown in the terminal title and session tab.
[FEATURE]: Show pending review indicator for sessions needing attention #27772 is about a notification dot for sessions needing user attention that disappears after navigation. This PR provides continuous real-time status (green/yellow/red) reflecting the current LLM/tool activity, not just pending user input.

Closing this issue — the feature has been implemented as a plugin. You can install it via the opencode-traffic-light plugin or directly from the repository at https://github.com/niushuai1991/opencode-traffic-light.
