Subject: [PATCH] fix: should allow autoCols=true when server doesn't provide
 size (#7132)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

set autoCols = true by default for Logs Terminal

## Changes
Previously, the logs terminal had autoCols: false to preserve
server-side progress bar rendering, However, this caused large black
empty areas when the server terminal was narrower than the UI panel,
Many server environments don't provide terminal size at all, making this
tradeoff not worthwhile.

The original implementation set autoCols: false because the server
renders progress bars based on its own terminal width. If the frontend
used a different column count, progress bars would display incorrectly
(e.g., wrapped or truncated).

However, this created a poor user experience:
1. The terminal only filled a portion of the panel width (often 80
columns)
  2. The remaining space appeared as a large black empty area
3. Many backend environments don't provide size data at all, making the
fixed-width approach pointless
