ReissuingBroadcastHandle's hot-swap iteration now opens its own
catalog.json publisher on every fresh session, pushes the manifest
once, and launches the same 2 s republish loop that
MoqLiteNestsSpeaker.startBroadcasting uses for the legacy
non-reconnecting path. Each iteration tears down the prior session's
catalog publisher + republisher AFTER the new pair is installed, so
watchers see at most a brief overlap rather than a gap when the
600 s moq-auth bearer triggers a session recycle.
Without this, the catalog goes silent the moment the wrapper recycles
the underlying session; any watcher that attaches AFTER the recycle
finds nothing to subscribe to even though the audio path is hot-
swapped seamlessly. With it, both audio and catalog survive every
JWT refresh.
Catalog teardown is also added to ReissuingBroadcastHandle.close()
because — unlike the audio publisher which broadcaster.stop() handles
internally — the catalog has no broadcaster wrapper.
