fix: session isolation and blocking wait for visual companion

Browse Source 
- Each session gets unique temp directory (/tmp/brainstorm-{pid}-{timestamp})
- Server outputs screen_dir and screen_file in startup JSON
- stop-server.sh takes screen_dir arg and cleans up session directory
- Document blocking TaskOutput pattern: 10-min timeouts, retry up to 3x,
  then prompt user "let me know when you want to continue"
