lenient multiple errors

✓ Passing This code compiles and runs correctly.

Code

// Test 052: Lenient parsing with multiple errors
// Parser should continue past errors and create parse-error nodes

~event valid-before {
    x: i32
}

// This event has an unclosed brace - should create parse-error node
~event broken-event {
    value: i32

// This event is valid - should still be parsed
~event valid-after {
    y: i32
}

// Another broken event - unclosed annotation
~[unclosed annotation event another_broken {
    z: i32
}

// One more valid event to verify recovery
~event final-valid {
    data: []const u8
}

Must fail at frontend compile:

Parsing or type-checking must reject the program.
