tests: HSMS connection concurrency / interleaved transactions

Public Access

Real GEM sessions don't serialize requests — the host can have many
primaries outstanding, replies may arrive in any order, and both
peers can talk at once.  Connection demuxes via system_bytes per
E37 §8.3; this commit pins the behaviour with four wire tests:

  - 5 in-flight requests; equipment buffers all primaries before
    replying — proves Connection holds the pending map correctly
    even when no replies are coming.
  - 7 pipelined primaries with synchronous in-handler replies;
    every host callback fires with the correct function and stream.
  - Bidirectional in-flight: host issues 3 primaries while equipment
    issues 3 of its own; all 6 callbacks resolve with the right
    replies.
  - 100-burst sequential cycle; confirms the pending_requests_ map
    doesn't leak entries (every reply delivered ⇒ map drained).

Closes #13 in the test-gap backlog.
