Closed via #78

$ ./exe/dead_end /tmp/scratch.rb

DeadEnd: Unmatched `end` detected

This code has an unmatched `end`. Ensure that all `end` lines
in your code have a matching syntax keyword  (`def`,  `do`, etc.)
and that you don't have any extra `end` lines.

file: /tmp/scratch.rb
simplified:

        5  module DeadEnd
        6    RSpec.describe "EndBlockParse" do
    ❯ 106      it "works with leading methods" do
    ❯ 123      end
    ❯ 124      end # HEREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
      211    end
      212  end

FWIW it looks like this was an issue with either heredocs or trailing lines (or a combination of both). Prior to #78 it was getting stuck here

lines 164, 165, 180, 181, are in a heredoc
