[Bug]: Monitoring dashboard handler can panic due to missing template function 'div'

[cotishq]

🐛 Bug Description

Current code path in monitoring/web.go:

• handleDashboard uses template.Must(template.New("dashboard").Parse(dashboardTemplate))
• dashboardTemplate includes {{printf "%.2f" (div .Metrics.MemAllocBytes 1048576.0)}}

This can panic at runtime when / is requested.

🔁 Steps to Reproduce

Steps to reproduce the behavior:

1. Enable monitoring (ENABLE_MONITORING=true)
2. Start the plugin
3. Open http://localhost:<MONITORING_PORT>/

@sanjay7178 I found a small bug in monitoring: the dashboard template uses a \div function but handleDashboard parses the template without registering it, which can cause a runtime panic (function "div" not defined). I can submit a small fix PR for this (register FuncMap + safer template parse error handling). Should I proceed with this issue?

@sanjay7178 Thanks for the clarification. I’ll hold off on the dashboard fix for now.If there’s a specific task we are prioritizing now, prefer me to work on next, I’d be happy to take that up.
