DebugAgentClient.call() hardcoded a 60s socket timeout that also bounded
recv(), so any continue_execution call asking for a longer wait (e.g.
waiting for a user to alt-tab) would time out on the client side while
the debug agent was still legitimately waiting. call() now accepts an
optional socket_timeout override, and the continue_execution tool passes
timeout + 30 so the client socket outlives the agent's own timeout + 10s
of headroom.
Also adds a round-trip test for encode_message/decode_message (the wire
contract between the two independently-built sides of this protocol),
and corrects the WatchpointSlots docstring, which overstated what
Wow64SetThreadContext does -- the agent actually arms the hardware
watchpoints via a native x64 SetThreadContext call, with the Wow64
variant used only for 32-bit register readback.
