drey 0.1.3

Fixed

• Content-Length is matched without regard to case, as header names are. Two
  spellings were accepted and CONTENT-LENGTH: was not, so a client using it
  got "LSP message without Content-Length header", a confusing way to report
  unexpected capitalisation. A field whose name merely ends in content-length
  is still ignored rather than parsed as the length.
• The test suites leaked daemons. A daemon detaches and only drey stop ends
  it, and the CLI suite never stopped what it started, so 8 survived every run.
  Dozens accumulated here over a day, the oldest at 18 hours, and the suite
  began timing out under the process pressure. The real-server smoke test
  leaked a daemon and a rust-analyzer too. Both now clean up.
