chore(master): release 2.1.0

[mender-test-bot]

---

2.1.0 - 2026-05-18

Features

• Implement port-forwarding protocol v2
  (MEN-5902) (a10882f) by @alfrunes

  The new protocol is identical to v1 except v2 does not stop and wait for
  message acknowledgement. This immensely speeds up the throughput
  especially for higher latency.
  Requires mender-server > 4.1 and mender-connect > 3.0. mender-cli will
  automatically fall back to v1 if the device does not report that it
  supports port-forwarding v2.

Refactor

• Lower cyclometic complexity of TCPPortforwarder
  (11c91e7) by @alfrunes
