Subject: [PATCH] fix(remoteplay): stub Initialize and GetConnectionStatus as
 disconnected (#536)

* fix(remoteplay): stub Initialize and GetConnectionStatus as disconnected

Titles probe Remote Play during pad/network bring-up; unresolved imports
returned NOT_FOUND. Report initialized + disconnected so callers take the
normal offline path.

* chore: retrigger gameplay CI for PR #536
