ifcviewer: move render() body into ViewportCore (#84-x)

Browse Source

The frame loop — surface acquisition, parallel cull dispatch, streaming
drive, two-pass main render, HiZ resolve, edge pass, screenshot
capture, FrameStats emission, interactive / bench heartbeat, bench
summary + auto-quit — all live in ViewportCore now.
ViewportWindow::render() shrinks to the Qt-only prelude:
isExposed() guard, fpsIntegrate() (fly-mode WASD step), then
core_.render().

The overlay renderer stays Qt-bound (OverlayRenderer.h carries
QString labels). Core reaches it via two new ViewportHost virtuals:
encodeOverlaysInMainPass (section gizmos, highlights, pivot, lines,
points — in-MSAA-pass) and encodeOverlaysPostMain (corner axis,
marquee, labels — on the resolved surface). The QtViewportHost
implementation in ViewportWindow forwards each to overlays_.X().

FrameStats moves to its own Qt-free header (FrameStats.h) with
ViewportWindow::FrameStats re-exported as a using-alias so the
bonsai-side signal binding keeps working. ViewportHost::onFrameStats
replaces the placeholder 4-double signature with the typed POD.
OverlayFrame moves alongside (OverlayFrame.h) so the host overlay
callbacks can carry it without dragging Qt into core.

Bench + frame-stats + cull-tuning state (min_pixel_radius_,
motion_min_pixel_radius_, lod1_pixel_threshold_, cull_threads_enabled_,
prev_camera_*, has_prev_camera_, last_cull_was_motion_, last_visible_*,
last_cull_*ms_, last_stream_ms_, bench_*, interactive_frame_count_,
frame_time_ms_window_/_sum_/_count_/_head_) move to ViewportCore; VW
keeps reference aliases so the env-var prelude, setBenchmarkFrames,
and the various tool keybind setters keep compiling unchanged.

Smoke checks: --screenshot path renders + saves a clean PNG;
--benchmark 10 runs the warm gate, prints the per-frame log + summary,
and exits cleanly via host_->quit().
