* feat(reader): swipe down to re-fetch a chapter, never cache empty responses
- pull down at the top of a chapter to re-fetch it, recovering from
transient empty responses without leaving the reader
- empty responses are evicted from the chapter cache so a refresh
re-fetches instead of replaying the empty message
- add a refresh button to the reader's bottom bar and a 'Refresh
chapter' link on the empty-chapter message
- register the typescript-eslint plugin and ignore assets/ in the
eslint flat config so lint-staged can lint core.js
* feat(reader): move refresh option to appbar menu
