multiple resources partial cleanup

✓ Passing This code compiles and runs correctly.

Code

// Test 521: Multiple resources - partial cleanup (MUST FAIL)
// Tests that the compiler catches when only ONE of TWO resources is cleaned
//
// Key points:
// - open_two() returns TWO files, each with [opened!]
// - We only close ONE file (file1)
// - ERROR: file2 still has cleanup obligation
// - This verifies each obligation is tracked independently

~import "$app/fs"

~app.fs:open_two(path1: "test1.txt", path2: "test2.txt")
| opened f |> app.fs:close(file: f.file1)  // Close first file only
    | closed |> _  // ERROR: f.file2 still uncleaned!

Error Verification

Expected Error Pattern

This test must fail because it opens TWO files but only closes ONE.
The second file (f.file2) still has a cleanup obligation at the terminator.
