chore(lotus): clear pre-existing lint/prettier debt ahead of the CI gate

`pnpm lint:eslint` and `pnpm prettier:check` were never run by fork CI (#5),
and lotus HEAD failed both: a missing return type in lotusDecorations, a
type-only import in lotusWidget, and formatting drift in lotusAudioInject,
lotusFocus, lotusWidget and .gitea/workflows/ci.yml. No behaviour change.
Both gates now pass clean so they can be turned on.
