Judging from your requirements for the app you're building - it sounds like maybe the core should be a typescript library handling the data and rendering - then wrapped in a (eg: react) component, wrapped in an app - similar to eg d3.js might be used?
That said, I've been trying to find a reasonable stack for our project at work - and I'm so far quite impressed with RedwoodJS - it appears to help with a lot of useful "opinions" - on testing, on styling and integration with storybook.
As this is a hobby project, I'd probably try to optimize the choice for fun/joy - so maybe clojurescript/reagent, maybe svelte, maybe elm - maybe even something like https://www.amber-lang.net/ (although, probably not...).
Finally, sounds like you will be wrangling some narly data structures (annotations on top of documents) - sounds like you might need "more" than just typescript for that - perhaps clojure is a good fit?
