chore(node): add workspace lints

Lior banned `as` repo-wide, unless absolutely necessary.

Nearly all as uses can be replaced with [Try]From which doesn't
have implicit coercions like as (we encountered several bugs due to these coercions).

Motivation: we are standardizing lints across the repo and CI,
instead of each crate having separate sets of lints.
