Problem

First completion request blocked the UI with three sequential synchronous vim.system():wait() calls (man page, command names, command list), and every subsequent completion unnecessarily deep-copied the entire cache.

Closes #1

Solution

Run all three system calls concurrently via vim.system callbacks, merging results when all complete. Queue pending completion requests during loading. Return cached items directly instead of deep-copying.
