Splits RenderBackend's per-voxel face-visibility extraction and tile shading out as GPU-offloadable steps (wgpu compute shaders), while keeping greedy-mesh merge/compaction CPU-only per the plan's "partial GPU rendering" design. RENDER_BACKEND=cpu|gpu|hybrid selects the strategy, falling back to cpu automatically (logged) if no compatible GPU adapter is found. Verified against a real GPU: all tests pass, including ones asserting byte-identical output between the cpu and gpu backends; a new benchmark example honestly shows cpu currently outperforming gpu/hybrid at realistic batch sizes since each call is its own dispatch/readback round trip rather than batched across a whole render batch (documented as a follow-up optimization). Also fixes two real, pre-existing gaps found while validating the worker's actual `docker build`: a missing .dockerignore was sending the local multi-GB target/ dir into the build context, and the Dockerfile's rust:1.80 pin was already too old for current transitive dependency MSRVs (bumped to rust:1.97).
