[bug] duplicate ProgressBar renders in non-centered Brain sidebar

[four-bytes-robby]

Problem

In the non-centered branch of BrainStatusBar (src/tui.tsx, around line 170-172), an orphan <ProgressBar> block was rendered below the main row. The ProgressBar inside the status row (lines 163-168) already provides the same visual; the extra block caused a duplicate progress display in the home_bottom slot.

Fix

Remove the orphan {current() > 0 && total() > 0 && (<ProgressBar ... />)} block from the non-centered branch. Keep the inline ProgressBar in the row, which mirrors StatusRow.
