Match reconnect behavior to the same lifecycle gates as initial connect

Summary#

Lifecycle-sensitive integrations become unstable when reconnect logic is broader than initial connection logic. If the first attach waits for a readiness event, the retry and reconnect paths should usually wait for the same signal, otherwise background replacement, duplicate registration, or race conditions appear only in edge browser states.

Problem#

A reconnect handler ran unconditionally during prerendering, even though the initial connect path already knew that attaching before page reveal was unsafe.

Solution#

Centralize readiness checks and reuse them for both first connect and reconnect flows, keyed to explicit platform lifecycle events such as page reveal or prerender completion. Add tests for uncommon phases like prerender, restore, and worker-driven reconnection rather than only normal page loads.

Failure Modes#

Reconnect storms or duplicate channel registration
Background workers evict a valid connection with a premature replacement
Bugs appear only in prerender, BFCache, or other nonstandard navigation phases
