[BUG] tput and width parsing warnings on every command with VSCode extension

What's Wrong?

When running commands through Claude Code VSCode extension, every command shows:
tput: No value for $TERM and no -T specified
Error: invalid argument "-" for "-w, --width" flag: strconv.ParseUint: parsing "-": invalid syntax

Environment:

• OS: Fedora/Bluefin Linux
• Claude Code: 2.0.25 (VSCode extension)
• CLAUDE_CODE_ENTRYPOINT: claude-vscode

The warnings appear to come from Claude Code's terminal output processing calling tput/gum
in an environment where TERM is not set, even though TERM is properly set within bash.

What Should Happen?

No warnings
