fix(capture): replay keeps its records, skips RakNet's own messages and waits for transfers

- the expected answers pointed into a copy of the records that was gone by the diff
- the client's recorded connect and disconnect messages are RakNet's, not sent again
- a recorded move to another world is waited for as long as a zone takes to start
- the handshake sends the client net version; reports are written after every bundle
- a crash or Ctrl-C of the tool stops the sandbox stack too
