Feature Request: Claude Code should handle terminal progress bars/spinners

Various command line applications (e.g. package managers) implement command line progress bars/spinners to indicate progress. It appears that currently Claude Code is just stripping the VT100 sequences that passing the full output to the model (at least judging by how quickly it ate through my context window). I think a better implementation would be to run the command output through a VT100 emulator and passing claude some representation of the rendered output.
