Append three host-readable sensor groups to the producer block, ABI
frozen by offset asserts (producer still fits page 0):
- cursor Tier-1 (hotspot, glyph dims, shape identity), published under
the existing cursor_seq gate
- content_change_ns: monotonic stamp of the last scene-content change
- display geometry on its own cache line under a geom_seq seqlock:
virtual-desktop bbox, captured-output origin, DPI, refresh
Source the cursor from each backend's existing grab metadata instead of
polling GetCursorInfo in the present pump: DDA from the duplication frame
info pointer position (no extra calls), NvFBC visibility from the grab
info plus one GetCursorInfo per frame for position, GDI from
GetCursorInfo. Position sampling now rides the frame rate, not the pump
tick.
Sample display geometry once at startup and re-sample only on backend
session recreate or a captured-mode change. Drop per-tick cursor
sampling (cursor_sample_pos) from the present loop.
Add src/stream/win32/geometry.{c,h}.
