Subject: [PATCH] perf: exit splash screen immediately after workspace.create()

Switch to the workspace view as soon as workspace.create() succeeds,
rather than waiting for sendMessage() to complete. The sendMessage RPC
is fired in the background since:

1. Stream errors are handled by the workspace UI via stream-error events
2. sendMessage returns quickly after kicking off the stream
3. The user can see the workspace UI while streaming starts

This reduces perceived latency by eliminating the sendMessage RPC
round-trip from the splash screen duration.
