nixd: code actions

• add undefined variable as top-level formal
• split an subexpression, with import ./file
• with ..; let / inherit

If I may request, a couple more:

• flatten attrset:

  { foo = { bar = "foz"; } };

  to

  { foo.bar = "foz"; }

• pack into nested attrset:

  foo.bar = "foz";
  foo.baz = "faz";

  to

  foo = { 
    bar = "foz";
    baz = "faz";
  };

Thanks, any more ideas are welcomed!

• "remove unused definition" for the warning definition X is not used (sema-def-not-used)

I use noogle.dev a lot. A "open in noogle.dev" code action would be neat for any function in the lib attribute set from nixpkgs

• add_to_top_level_lambda_param
  Add an undefined name to the top-level lambda.

{ foo }: foo + bar

=>

{ foo, bar }: foo + bar

• quote_attr and unquote_attr
  Rewrite between attribute names and double quoted strings

{ foo = bar; }

<=>

{ "foo" = bar; }
