[FEATURE] Add PR title to status line

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

When opening one of my many terminal tabs, I sometimes have a hard time remembering what I'm working on

Proposed Solution

Claude code renders a "PR #<pr number>" under the input. I'd like it to render next to that the GitHub PR title as well, so that I can more easily recognize what my current session is working on. Ideally it also adds indication whether the PR is in draft/open/merged/closed state. There is enough space available on that line as noting else is rendered on it.

Alternative Solutions

I currently have programmed this in my statusline, but it's duplicate information. There already is a line reserved for "PR #<number>" may as well add more info in it

_edit: just noticed I can turn off the PR line in the settings_

Priority

Medium - Would be very helpful

Feature Category

Interactive mode (TUI)

Use Case Example

_No response_

Additional Context

Now I have

But ideally that bottom line just contains the PR title as well
