Wait for the initial pause render before completing debugger REPL
startup, but only when the initial pause is actually observed during
startup initialization.
Creating the wait promise before Runtime.runIfWaitingForDebugger() can
hang when the debug target exits or disconnects without producing an
initial pause event. It also assumes the inspector object always has
parsed CLI options, which is not true for tests that use a minimal mock
inspector.
Create the initial-render wait lazily from the Debugger.paused handler
while startup initialization is active. This preserves prompt ordering
for normal initial breaks without blocking startup when no initial pause
render occurs.
