* perf(weed/topology): keep only volume ids in the heartbeat membership set The map is used solely to test whether a known volume is still present, but it copied the whole 152-byte VolumeInfo for every volume in the heartbeat. Presize it too, since the count is known.

At 100k volumes that is a 15MB copy per heartbeat to usually find nothing. Scan the disk maps in place instead and return only what was removed.
