The cross-platform half of the gap sweep:
* Phase-locked capture reaches the DESKTOP clients (it shipped on
Apple/Android only, though the desktop presenter has the best latch
signal of all — true on-glass stamps via VK_KHR_present_wait). The
presenter's 1 Hz fold publishes a latch grid (anchor = last on-glass
instant; period = min positive present spacing, capped by the display
mode's refresh so an arrival-paced sub-panel-rate stream can't claim a
slower grid); the session pump folds every AU's arrival stamp against
it with the SHARED `phase::circular_latch` statistic and sends the
~1 Hz PhaseReport (1 ms uncertainty — reference-client parity). The
cap is advertised only when present timing is real
(`VulkanDecodeDevice::present_timing` gates `SessionParams::phase_lock`),
and the host's applied grid offset from the 0xCF tail is logged so an
on-glass run can watch the controller engage.
* `Hello::display_hdr` stops being hardcoded `None`: Windows reads the
panel's colour volume from DXGI (`IDXGIOutput6::GetDesc1`, the
`--window-pos` output else the primary, advanced-color outputs only,
gated on the HDR setting) so the host's virtual-display EDID matches
the real glass. Linux keeps the EDID defaults — no portable
Wayland/X11 query exists — and the comment now says exactly that.
* The console settings screen (the ONLY editor in Gaming Mode) learns
the rows it was missing: render scale, full chroma 4:4:4, invert
scroll, capture system shortcuts, fullscreen-on-stream, auto-wake and
the game-library toggle.
* A spec-run session's device picks (GPU adapter, speaker, microphone)
now come from the `--resolved-spec` instead of a raw Settings load —
the last store read the spec path still owed (§5), and what would
make those fields profileable.
* `session_args()` documents why the GTK/CLI spawners pass no
`--window-pos` (Wayland exposes no global coordinates to read and SDL
can't apply them).
