Agent Skills: rounding-up-worktree-sessions

Use when scattered Claude Code sessions need to be found, grouped by effort, relocated to the right worktree's resume picker, or reopened together. Triggers: 'round up my sessions', 'find my worktree sessions', 'reopen my claude sessions by worktree', 'reorient sessions', 'relaunch sessions', 'resume my recent sessions grouped by worktree', 'my sessions are scattered', 'open all sessions for this effort'. NOT for: relocating a project's sessions because the CODE moved (use move-project); creating worktrees (use using-git-worktrees).
