HInts are cut / truncated (with tsserver)

[Avishayy]

I'm posting this mostly because I was googling and couldn't find a quick answer so hopefully for future googlers this will be helpful.

I dumped the client response (and made sure we don't set a length limit anywhere), and eventually found the implementation PR for tsserver and took a look, they set 30 as a hard limit, no idea why or whether it will change (I asked)

Perhaps it can be helpful to edit the README to let users know.

Sure, PRs welcome
