Description

I'd like to be able to use go-to-definition with record fields

pub type Thing {
  Thing(a: String)
}

pub fn work() {
  let x = get_thing()
  x.a // go-to-def here!
}

I started working on this in #5533, with some Discussion in the Gleam Discord here

Contributor guide

Research direction
Examine the existing LSP go to definition implementation for other constructs, review the previous attempt in PR #5533, and understand how record fields are resolved in the compiler's type checking phase.
