Module completion 

Synchronous completion utilities for async FFI callbacks

This module provides a generic mechanism for blocking on async Swift FFI callbacks and propagating results (success or error) back to Rust synchronously.

Example

use screencapturekit::utils::completion::SyncCompletion;

// Create completion for a String result
let (completion, _context) = SyncCompletion::<String>::new();

// In real use, context would be passed to FFI callback
// The callback would signal completion with a result

// Block until callback completes (would hang without callback)
// let result = completion.wait();
