Add StreamingRenderer class that implements stable prefix + unstable suffix pattern for incremental command output rendering. This reduces visual flicker during long-running tasks like npm test or pytest. - StreamingRenderer class with update/render/clear methods - Helper functions for terminal control (erase_lines, move_cursor_up) - 18 test cases covering all functionality Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Design
Lines ending with
\nare considered "stable" and will not be re-rendered. The last line (without a trailing newline) is considered "unstable" and will be updated on each render. This pattern is borrowed from Claude Code's approach to handling streaming output.Test plan
