What steps can reproduce the bug?

````
Rider:

        server.Hooks.On<MonsterAggroEvent>()
            .Where(e => e.Distance <= 4)
            .Select(e => e.MonsterId)
            .Run((monsterId, ctx) => ctx.Messages.Send(monsterId, "calm:inline"));

debug values:

e_MonsterId = {String} monster-1
e_PlayerId = {String} player-2
e_Distance = {I32} 3
e_MonsterLevel = {I32} 8
e_PlayerLevel = {I32} 3
$dotboxd.select.5700 = {String} <unassigned>

• e_* should be an expandable tree item showing properties like in a real debugger
• Run: monsterId is not visible in the debugger. Trying to evaluate it yields `org.eclipse.lsp4j.jsonrpc.ResponseErrorException: Unknown or unassigned sandbox variable 'monsterId'.`
• I want to see whats in ctx like in a real debugger
• I want intellisense showing me the properties inside a variable

Try to also apply to vs26
