After T10 shipped (commit 0ba3c59) several docs still claimed the
gbm_bo_map / ENBOXER_ENABLE_TOPLEVEL path was a stub, follow-up, or
"/dev/dri/renderD128 + new dep" work that never happened. Rewrite:
- README.md: ENABLE_TOPLEVEL row no longer says "unset = stub".
- docs/VIDEO.md: live toplevel-export is real (gbm_bo_map via
runtime dlopen of libgbm.so.1, real RGBA8 PNG via the png crate).
- CHANGELOG.md: T10 follow-up entry rewritten as shipped.
- docs/MACROS.md: stale "Forever is not out yet / later helper
(not shipped)" paragraph rewritten to point users at the
per-character GUI rebind instead.
