Capturer::rgba becomes offscreen() (sizes, error scopes, MSAA, depth,
read-back) plus finish() (background and labels), so another painter,
such as the window's paint callback, can draw into the same pass.

The drawing tests skipped silently without an adapter. Under
FIELDCRAFT_REQUIRE_GPU=1 they fail instead, and the snapshot and MCP
screenshot tests require a GPU renderer. CI runs them with
FIELDCRAFT_GPU=software on lavapipe.

render::draw_labels draws a scene's labels over finished pixels in the CPU
rasterizer's font. capture::shared opens the process's device once by the
FIELDCRAFT_GPU policy; capture::png draws on it or on the CPU and reports
which (Renderer).

fieldcraft-cli snapshot script.json --out shot.png [--view] [--size WxH]
draws the engine's framed scene (engine::view::frame, shared with the CPU
render_png) with the viewport's GPU pipelines offscreen: hardware GPU, then
a software one, then the CPU rasterizer (FIELDCRAFT_GPU=auto|hardware|
software|cpu). CI installs lavapipe so the GPU path runs there.

ui-egui keeps only the egui_wgpu paint callback; the shaders, batching and
pipelines are fieldcraft-gpu's view module, so an offscreen picture can draw
with the window's pipelines.
