- Add an `icons:arma` tool (extractArmaIcons.ts) that pulls inventory icons
out of the game's PBOs and materializes the .paa files the catalog needs.
- Extend the catalog import library with the matching planning and upsert
support, and cover it with integration tests.
Move the record contract, planning, and upsert logic out of the CLI script
and into src/lib/arma-import/catalog.ts so it can be unit-tested and reused.
The CLI (importArmaLibrary.ts) becomes a thin wrapper. Records are upserted
into assets (keyed by className) and vehicles (by classname); thumbnails are
materialized from .paa inventory icons, and fuel config is resolved per
record type. Adds integration coverage for the catalog import path.
