chunkFileNames names the chunk holding src/globe/navara
navara-engine-[hash].js; chunking is unchanged (manualChunks would pull
modules shared with the Cesium entry into it and make the entry import
it). The Cesium main chunk stays 2,849,217 B.
The import-direction check now tells dynamic imports apart
(analyzeModule(source, { dynamic: true })) and rejects any static import
or re-export of src/globe/navara/** from outside that directory, so the
Navara engine can only be a lazily loaded chunk of the app.
Navara's prebuilt workers load their wasm by file name next to
themselves, which the bundler cannot see; a build-only Rollup plugin
copies the missing ones (draco decoder, font worker) into assets/ when
the bundle includes Navara, and adds nothing to a build without it.
