Commit Message

test: deterministically cover serial Manager.reconnect branches (#56)

- add TestReconnectContextCancelledBeforeSleep: already-cancelled ctx
  hits the pre-sleep ctx.Done() check deterministically (no timing)
- add beforeReconnectSleep, a nil-guarded test-only hook invoked in
  reconnect just before each backoff sleep (no-op, zero cost in
  production)
- rewrite TestReconnectExitsOnGenMismatchDuringSleep to use the hook:
  it bumps gen synchronously right before the sleep, so the post-sleep
  gen check (serial.go:230-233) deterministically trips every run
  instead of racing a background goroutine against the sleep window;
  asserts OpenFunc is never called to prove the branch was actually
  taken, not that a fallback dial merely failed
- add TestReconnectSetReadTimeoutErrorContinues: a failing
  SetReadTimeout closes the dialed port and continues to the next
  delay slot
- add TestReconnectExitsOnGenMismatchAfterDial: OpenFunc bumps gen
  synchronously before returning, deterministically hitting the
  post-dial gen check without assigning the stale port to sm.port
- add mockPort.setReadTimeoutErr (test-only) so SetReadTimeout can be
  scripted to fail

reconnect coverage is 100.0% and identical across 5+ repeated runs —
closes the flaky zero-tolerance Coveralls gate on unrelated PRs.
