Module output_blocks 

Output formatting utilities for nicely rendered command blocks

Provides “timeline” format: a width-independent, lossless output format that works in TTY, tmux, SSH, CI, and logs.

Core concepts:

• │ prefix → tool metadata (timeline marker)
• $ → executed command (virtual or user command)
• No prefix → program output (stdout/stderr)
• Result marker (✓ / ✗) appears after output
