Run this Python script to check versions:

python3 - <<'PYEOF'
import urllib.request, os, sys

script = os.path.join(os.path.expanduser("~"), ".claude", "statusline.py")
url    = "https://raw.githubusercontent.com/Nipeno/ccstat/main/statusline.py"

# Get current version
current = None
if os.path.exists(script):
    with open(script, encoding='utf-8') as f:
        for line in f:
            if line.startswith("VERSION"):
                current = line.split('"')[1]
                break

if not current:
    print("ccstat is not installed. Run /ccstat-setup first.")
    sys.exit(0)

latest = None
