Expand description

Updates the given note commitment tree with all newly read note commitments starting at the block frontier_height + 1.

If anchor_retention is Some, every checkpoint the policy retains is kept as a durable anchor.

This is generic over the [ShardStore] backing the tree, so stores that maintain their note commitment trees by other means (for example, accumulating updates in memory and flushing them in bulk) can reuse the exact tree-update logic that put_blocks applies.
