Resolving a nested node used to collect every track before the queue
changed: one broadcast at the very end, playback only after the full
walk, and the playback loop blocked for the duration. Now provider
resolution streams bounded chunks (tidaldy: one per 50-track page), the
playback loop applies and broadcasts each chunk as it lands, playback
starts with the first chunk, and Replace/Clear cancel in-flight
resolves down to the HTTP fetch. Queue.resolving (additive proto field)
drives an animated-dots pseudo-item in the TUI queue pane.
Also fixes Enter on a non-queueable library item blanking the queue
while audio kept playing, and the reversed album order left by the old
LIFO walk.
