Koichi ITO 5ce308b082 Deliver subscriptions/listen notifications only after the acknowledgement 
## Motivation and Context

Per SEP-2575, the server MUST NOT send any notification on a subscription before `notifications/subscriptions/acknowledged`.
The listen stream was registered in the delivery registry before its acknowledgement was written (the write happens outside
the lock so a stalled reader cannot block the transport), so a change notification published concurrently from another thread
could be written to the stream ahead of the acknowledgement.

The entry is now inserted inactive - still reserving the id and the cap slot atomically - and becomes eligible for delivery only
after the acknowledgement write has completed. A concurrent notification inside the window skips the inactive entry,
which is indistinguishable from the change happening just before the subscription opened.

## How Has This Been Tested?

With a new regression test pinning the window (an entry injected in the registered-but-unacknowledged state receives nothing until activation),
the full suite, RuboCop, and the conformance suite, all green.

## Breaking Changes

None. Activation happens synchronously inside the same response body proc, so an acknowledged stream behaves exactly as before.
