Fresh-start block-production stall root cause. The node-side notification
bridge (node/chains/manager.go) calls VM.WaitForEvent in a loop with a
non-cancellable context.Background(), starting BEFORE SetState(NormalOp)
initializes vm.builder. The first WaitForEvent therefore parks in the
builder==nil select { ctx.Done | stateSyncDone | shutdownChan } and, since the
context never cancels and state-sync is off, blocks FOREVER -- the serial
bridge loop never re-calls WaitForEvent to observe the now-ready builder, so no
PendingTxs ever reaches the engine and no block is ever built.
ava avoids this with common.NotificationForwarder + cn.OnChange=CheckForEvent,
which cancels the outstanding WaitForEvent and re-subscribes on VM state change.
Lux replaced that with the hand-rolled bridge and lost the recovery path.
Fix (self-contained, VM-side): add builderReady chan, closed once by
onNormalOperationsStarted after vm.builder is set, and add a select case so a
WaitForEvent that parked early re-fetches the ready builder and proceeds.
Makes WaitForEvent correct for any caller, cancellable or not.
