029 - Issue 281 Contract Repro

Goal

Add a contract test that reproduces issue #281: after changing a tunnel's entry node, forward runtime cleanup does not remove the stale service from the old entry node.

Checklist

• Review existing contract test helpers for mock node command recording.
• Add a contract test that updates a tunnel entry node while a forward is bound to the tunnel.
• Assert the new entry node receives forward sync commands and the old entry node does not receive forward cleanup, reproducing the bug.
• Run the focused contract test and capture the failure.

Test Record

• Command: cd go-backend && go test ./tests/contract/... -run TestTunnelUpdateChangesEntryNodeButLeavesOldForwardRuntimeContract
• Result: failed as expected with expected old entry node to receive forward DeleteService cleanup for 1_2_281, got none.
