drey 0.1.7

Fixed

• The guard against a server config pointing back at drey itself now checks
  the exact executable path instead of banning its whole parent directory.
  Homebrew installs drey at /usr/local/bin/drey, the same directory as
  asdf and every other server binary it manages; drey install correctly
  points asdf-managed servers at /usr/local/bin/asdf
  (command = "/usr/local/bin/asdf", args = ["exec", "rust-analyzer"]), but
  the guard read that as drey pointing at itself and refused to spawn it. Six
  of the twelve built-in servers route through asdf, so this hung silently for
  anyone with drey installed next to a version manager in the same directory,
  the same "attached to nothing, no error" symptom as 0.1.5's shim loop.
