Enforce the lifecycle rule that the server SHOULD NOT respond to a request
(other than ping) before the client has sent notifications/initialized.
With this enabled, a stateful session that receives e.g. tools/list after
the initialize response but before notifications/initialized is rejected
with -32002. initialize and ping are always allowed; the stateless path
(which has no per-session initialized handshake) is exempt. OFF by default
— the rule is a SHOULD and well-behaved clients send initialized
immediately.
