[FEATURE] Allow to click on teammate messages to expand them with CLAUDE_CODE_NO_FLICKER=1 / have an env var to have them expanded by default

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Right now we have to press ctrl+o to see what messages were sent from a teammate to the other. This is very annoying. CLAUDE_CODE_NO_FLICKER=1 allows to have interactive elements that expand when clicked.

Proposed Solution

When CLAUDE_CODE_NO_FLICKER=1, allow that clicking on a teammate message expand it. Also an env variable "CLAUDE_CODE_EXPAND_TEAMMATE_MESSAGE=1" that would default to showing the full messages in the viewer would be nice to increase monitorability
