        Scripts are fleet-wide C# expression compilations referenced by virtual tags and scripted
        alarms. The editor provides Roslyn-backed IntelliSense — completions, diagnostics, hover,
        and tag-path suggestions for <code>ctx.GetTag</code> / <code>ctx.SetVirtualTag</code> literals.
