Rebase the current branch.

Arguments are provided in the user's message.

Behavior:

• No arguments: rebase on the current branch's workmux base branch (git config branch.<current>.workmux-base), falling back to local main when none is configured
• "origin": fetch origin, rebase on origin/main
• "origin/branch": fetch origin, rebase on origin/branch
• "branch": rebase on local branch (use "main" to force a rebase on local main)

Steps:

1. Parse arguments:
   • No args → target is the current branch's workmux base branch (git config --get branch.$(git branch --show-current).workmux-base); if that is empty, target is "main". No fetch.
   • Contains "/" (e.g., "origin/develop") → split into remote and branch, fetch remote, target is remote/branch
   • Just "origin" → fetch origin, target is "origin/main"
   • Anything else → target is that branch name, no fetch
2. If fetching, run: git fetch <remote>
3. Run: git rebase <target>
4. If conflicts occur, handle them carefully (see below)
5. Continue until rebase is complete

Handling conflicts:

• BEFORE resolving any conflict, understand what changes were made to each conflicting file in the target branch
• For each conflicting file, run git log -p -n 3 <target> -- <file> to see recent changes to that file in the target branch
• The goal is to preserve BOTH the changes from the target branch AND our branch's changes
• After resolving each conflict, stage the file and continue with git rebase --continue
• If a conflict is too complex or unclear, ask for guidance before proceeding
