042 capture if for multi

// Test: Capture with if inside for - PURE KORU (no custom events/procs)
// This is the pattern shown in the blog post:
// - Capture multiple fields (sum and count)
// - Iterate with for
// - Conditionally update with if
// - Print result with std.io:print.ln
//
// Items to iterate over: 1, 3, 6, 8, 10
// Values > 5: 6, 8, 10 (sum = 24, count = 3, avg = 8)
