Update - Restart Vellum (with Smart Branch Handling)

Restart the Vellum assistant and gateway services with branch-aware git behavior.

Arguments

The user may pass $ARGUMENTS to control branch behavior:

Steps

1. Ensure Bun is on PATH:
   `bash
   export PATH="$HOME/.bun/bin:$PATH"
   `

2. Preflight snapshot - capture current state before making changes:
   `bash
   vellum ps
   `

3. Quiesce with vellum sleep - stop assistant and gateway processes. This is directory-agnostic and stops processes globally regardless of CWD:
   `bash
   vellum sleep || true
   `

4. Verify stopped - run vellum ps and confirm no running processes. If vellum ps shows processes still running, run fallback cleanup to force-kill them:
   `bash
   vellum ps
   `

   Fallback cleanup if vellum ps confirms processes are still running:
   `bash
   pkill -x "vellum-assistant" || true
   pkill -f "gateway/src/index" || true
   lsof -ti :7830 | xargs kill -9 2>/dev/null || true
   lsof -ti :7821 | xargs kill -9 2>/dev/null || true
   `
   After fallback cleanup, run vellum ps again to confirm all processes are stopped.

5. Smart branch handling - determine what git operations (if any) to perform:

    CURRENT=$(git branch --show-current)
    GIT_OPS_RAN=false

   Case A - --pull flag: Force pull on the current branch.
   `bash
   if [[ "$ARGUMENTS" == "--pull" ]]; then
   git pull
   GITOPSRAN=true
   fi
   `

   Case B - Explicit branch name provided: Check out the requested branch, pulling if possible. Before checking out, verify the working tree is clean - if there are uncommitted changes, stop and warn the user rather than silently losing work. Do NOT stash automatically.
   `bash
   if [[ -n "$ARGUMENTS" && "$ARGUMENTS" != "--pull" ]]; then
   if ! git diff --quiet || ! git diff --cached --quiet; then
   echo "ERROR: Uncommitted changes detected. Commit or stash them before switching branches."
   # Stop and report the error to the user. Do not proceed.
   fi
   git checkout "$ARGUMENTS"
   git pull origin "$ARGUMENTS" 2>/dev/null || true
   GITOPSRAN=true
   fi
   `

   Case C - No args, on main: Pull latest from origin (preserves current default behavior).
   `bash
   if [[ -z "$ARGUMENTS" && "$CURRENT" == "main" ]]; then
   git pull origin main
   GITOPSRAN=true
   fi
   `

   Case D - No args, on a feature branch: Skip git ops entirely - just restart with the current checkout.
   `bash
   if [[ -z "$ARGUMENTS" && "$CURRENT" != "main" ]]; then
   echo "On branch '$CURRENT' - skipping git pull, restarting with current checkout"
   fi
   `

6. Install dependencies - only if git operations ran (dependencies are unlikely to have changed for a local-only restart):
   `bash
   if [[ "$GITOPSRAN" == "true" ]]; then
   cd assistant && bun install && cd ..
   cd gateway && bun install && cd ..
   fi
   `

7. Restart with vellum wake - start assistant and gateway from the current checkout. vellum wake must be run from the checkout directory that should supply the new assistant code:
   `bash
   vellum wake
   `

8. Verify fresh state - run vellum ps to confirm processes are running:
   `bash
   sleep 5
   echo ""
   echo "=== Startup Summary ==="
   vellum ps
   echo "======================="
   `

Report

Tailor the report to what actually happened:

• If git pulled (Cases A, B, C): Report what was pulled (new commits), the branch, and whether dependencies were updated.
• If restarted in-place (Case D): Report that services were restarted on the current branch with no git changes.
• Always include: The startup summary block output (assistant health, gateway health).
