pwa-assets.config.ts stages the brand logo in public/icons/.brand-source.*
so the CLI (which emits next to its source) writes alongside it. Without
cleanup, the full-resolution 1024+ source ends up in dist/icons/ on every
build and is publicly served at /icons/.brand-source.png.
scripts/generate-pwa-assets.mjs runs the CLI, then removes the staged
source. Wire it through the `generate-pwa-assets` pnpm script.
Part of aiolabs/webapp#95.
