patch() turns corrupt-manifest struct/index errors into FrameError; a missing
layer build says so; the signing key falls back to a rename where hard links
aren't supported and explains how to recover from a bad cached key; the layer
nulls an instance it can't destroy and logs xrLocateSpaces once.
Not changed: the 1.1 Meta profile names match xr.xml's promoted names
(meta/touch_pro_controller, meta/touch_plus_controller), and grip_surface is
palm_ext renamed, so the rewrite stays (now commented).

Quest apps ask for 72/90/120/144 Hz; SteamVR offers only the current rate and
Wolvic aborted on XR_ERROR_DISPLAY_REFRESH_RATE_UNSUPPORTED_FB. Verified on
the Frame: Wolvic's Quest build now reaches XR_SESSION_STATE_SYNCHRONIZED.
