Workflow

Step 1: Gather Context

1. Determine the main branch:

   git symbolic-ref refs/remotes/origin/HEAD | sed 's@^refs/remotes/origin/@@'
   

   Falls back to main or master if not set.

2. Find the merge base:

   MAIN_BRANCH=$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@' || echo "main")
   MERGE_BASE=$(git merge-base HEAD origin/$MAIN_BRANCH)
