Rebase Downstream Tree

Rebase a tree of dependent branches after upstream changes have been made. Auto-detects the downstream branch tree (including sibling branches), rebases each branch in order, resolves conflicts when possible, and runs preflight checks on each branch.

Current State

• Branch: !git branch --show-current
• Status: !git status --short

Steps

1. Detect current branch

Get the current branch name. This is the branch that was just modified and whose changes need to propagate downstream.
