simplify tools: shared harness setup (pipeline, block proxy, render job, framing, record copy, label cells, contact sheets) for the standalone renderers and the benchmark, block-entity scenes as name/yaw records, one dump pipeline for mob and avatar renderers with a shared submit helper, transform record and jem/entry/subset helpers, posed block entities from direct layer constants, pptest scenes registered once with settle-tick and resolution tables and put() for all blocks, jdk detection and full error log in the dump script, pptest jar rebuilt instead of updated, gradle task printing the tool classpath, comments trimmed
