fix(stream): collapse terminal redraw controls

[YOMXXX]

Summary

• collapse common terminal redraw controls before captured output reaches filters
• handle carriage-return progress rewrites and backspace overwrites for exec_capture and run_streaming capture/filter paths
• preserve normal CRLF line endings while avoiding transient progress/spinner states in model-facing output

Fixes #2230
