fix: replace jimp with selective @jimp/* imports to fix ESM crash (#333)

The full `jimp` package pulls in `@jimp/plugin-print`, which has a
broken ESM default import of `simple-xml-to-json` — crashing on
`npx` startup (Node 22+). We only use read, crop, and write, so
import `@jimp/core` with just the plugins and formats we need.

Closes #329
