描述

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

研究方向
Examine the previous work in #5533 to understand the approach taken for go to definition on record fields. Review the Gleam compiler's AST representation for record fields in the type checking phase. Look at existing LSP handlers for go to definition in the codebase to see how other definitions are resolved. Implement the necessary logic to map field access to the field definition in the record type.
