Glass 'keymap regression' triage: stale build-glass exe, not code — rebuild + full re-verify

The live-reported glass regressions (arrows dead / lever+detent missing /
V+J/K/L+N inert / weapons into the ground) were build-glass/Release/btl4.exe
built at 07:47 running the pre-5dd3536 image: no suppression tables, no V/J/K/L
keys, unpinned RIO ids.  content\bindings.txt already carried the merged map
(arrows = W/S lever + A/D pedals) and parsed clean.  Clean rebuild closed every
symptom; SendInput re-verification: lever holds on release + stops at zero,
LEFT/RIGHT turn in MID (wire-sign correct), V toggles with BT_SHOT pair, level
boresight at spawn, R/F elevation drive; pod build rebuilt + smoked un-regressed.

Code delta: BT_MPPR_TRACE [mppr-c] line enriched with mode/pedals/stick/turn/elev
so one env-gated line proves the whole control surface.
