ultraindex-nav — navigate a huge repo through its index

This is the light consumer of an ultraindex build. Instead of reading a large repo into context, you ask the prebuilt index where to look and open only what the task needs. The same zero-dependency bundle ships here: node scripts/ultraindex.mjs <command>. No npm install, no keys.

The core rule: load the minimum. Use find to get the exact files, open those entries/files one at a time, and answer. Do not read graph.json or the whole encyclopedia/ directory — that defeats the purpose.
