[FEATURE] Status line should render immediately on startup, not after first assistant message

• [x] This is a single feature request (not multiple features)

Problem Statement

The status line currently only renders after the first API interaction (assistant message). It would be great if it rendered immediately when a conversation starts, so the user sees model, context, project, and branch info right away without having to wait for the first response.

Current behavior: status line is blank until first assistant message.

Proposed Solution

status line renders on startup with available info (model, project dir, git branch, etc.).
