Skill: merge-worktree

Purpose

Automates the batch worktree lifecycle from the main repo: scan all active linked worktrees, let the user select which to merge, verify all selected are clean, merge and push each in sequence, then remove all successfully-merged worktrees together. Eliminates the need to cd into each worktree directory and invoke a merge operation separately.

Core Objective

Primary goal: From the main repo, land all selected worktree branches onto main, deliver them to origin, and clean up — leaving the repository in a clean state.
