useWebSocket's ready handler calls loadMessages(channelId, true) from
two adjacent code paths in the same handler invocation (remote-space
refresh + per-origin cache clearing). Both fired in parallel because
force=true bypassed dedup, producing the duplicate /messages requests
visible in playwright network traces even after the parallel-mount
dedup landed.
Coalescing force=true with an in-flight call is safe: the requests hit
the same endpoint with the same params and would return the same data,
and the force caller still gets a fresh result via the shared Promise.
