Patch Changes

• 117531d: Add getTopic() to TopicQuery for parity with getPath() on RESTQuery. The static topic template only supports fixed-shape topics, so consumers with variable-segment-count or conditionally-shaped topics had to hand-author one query class per shape. Subclasses can now override getTopic() to compute the topic dynamically at execution time over the resolved params (e.g. 'layout:' + this.params.segments.map(encodeURIComponent).join(':')); when defined it takes precedence over the topic field. The topic field is now optional, matching path? on RESTQuery. Existing queries that define topic as a static template continue to work unchanged.
