Create PR to $ARGUMENTS

Create a pull request following Git best practices:

Steps:

1. Sync & Branch: Update main + create feature branch with appropriate prefix
2. Commit: Stage relevant files + commit with conventional message and sign-off
3. Push & PR: Push branch + create ready PR with detailed description

Target:

• If $ARGUMENTS provided: use as target repo/branch
• If empty: default to upstream/main

Commands to execute:

# Set target
TARGET=${ARGUMENTS:-upstream/main}

# 1. Sync & Branch
CURRENT_BRANCH=$(git branch --show-current)
if [[ "$CURRENT_BRANCH" == "main" || "$CURRENT_BRANCH" == "master" ]]; then
    # Sync with upstream first
    git fetch origin
    git pull origin main
    
    # Create feature branch with prefix
    # Choose: feature/, fix/, docs/, chore/, refactor/, test/
    git checkout -b feature/descriptive-name
fi

# 2. Stage & Commit with conventional format
git add path/to/relevant/files
git commit -s -m "feat: descriptive title

# 3. Push & Create PR
