chore(brand): lint the new package

@elide/brand shipped without a lint config while the repo lints its other TS
package, so its source and build scripts were unchecked. Mirrors the
packages/ui flat config, splitting environments: src is environment-neutral
(it has to run in a browser, in Node, and in a build script) while scripts is
Node-only tooling that never ships.

Clean on the first run — no code changes needed.
