test: cover plugin lock-release and discovery shutdown; fix Middleware godoc

- add TestConductor_MiddlewareReleasesLockDuringCall: a blocking plugin RPC,
  asserting a write-lock op succeeds while the call is in flight (proves the
  read lock is released before the RPC, not held across it)
- assert run() returns well under the 5s shutdown bound on the error path,
  proving discovery's ctx is cancelled before the wait
- correct Conductor.Middleware godoc: a call error returns HTTP 500 and stops
  the chain, a reply status >= 400 stops with that status
