Vouch request: Rushit

[Rushit]

What do you want to work on?

I'd like to fix #2120. I was using OpenShell to host a simple website out of a sandbox, I also bump into similar issue where TUI start throwing random logs and mine was trigger by network issue and loosing connection between gateway and terminal. I looked into it. The CLI logs to stderr for everything, and the TUI draws to that same terminal, so when a background call fails the warning gets printed right on TUI.

Draft - https://github.com/NVIDIA/OpenShell/compare/main...Rushit:OpenShell:fix/2120-tui-log-to-file?expand=1

Why this change?

I feel it's simple fix and it keeps me annoyed me enough on different issues when gateway not reachable or back end not accessible. Also, the approach to log into file -
• Fixes UI corruption: No more log spam breaking the layout. Also, TUI renders error in line, keeping stable UI and keepig user with right error message.
• Maintains consistency: Matches how OpenShell already handle logs / error across.
• Improves debugging: a TUI dev/user/agent can actually read them or tail -f them in another terminal.
