End-to-end Signal integration testing for coop. Use after implementing or fixing any Signal-related feature, provider interaction, or tool behavior to verify it works through the real Signal protocol and LLM API — not just unit tests. Sends real Signal messages, reads traces, diagnoses failures, and iterates until the feature works.

Validates the Coop TUI by capturing output from a tmux session using freeze and applying LLM-as-judge semantic validation. Supports text and visual (PNG/SVG) validation modes.
