Tcp server fix

[xuhz]

we don't have a better solution in npu to set debugger q

1. they have difficulty configuring active hw ctx
2. need more thinking / discussion to disable hws during debug

before we have a better solution, we change to

1. attach the debugger q before ctx runs
2. cert checks the q only when it detects a control code hang

this is still a good/useful feature to debug a control code hang though. better than nothing.
