/**
 * split-exec — Execute a split plan produced by split-plan.
 *
 * Reads a .split-plan.md file, clones the source branch, then for each split
 * (in order): checkout the target branch (existing PR or new branch from base),
 * cherry-pick the listed commits, push, and create a new PR when the plan says
 * "New PR". Processes one split at a time so the user can fix conflicts or stop.
 *
 * WHY initOutputLog({ prefix: 'split-exec' }): Separate logs from split-plan/prr/story.
