~anthropic/claude-sonnet-latest → A (6:4)

Side A removes a large, fragile, over-engineered keystroke-parsing graph (1800+ lines) and replaces it with a small, correct paste-and-go implementation plus matching tests/UI simplification, net reducing complexity while preserving functionality. Side B is a reasonable simplification (removing unused room visibility) and adds a room-create CLI path, but it's smaller in scope and mostly plumbing/cleanup rather than a substantive architectural fix.
