bind hosted joint surfaces and certify native normal accuracy

Compose the shared two-normal map with the physical LU host and its common
routing offset. Retain original surface equations and one canonical proposal
through physical precision rescue. Bound original-normal displacement and
host residual with the existing directed ray arithmetic for amplitudes and
cross sections, charging verification to sampling time.

Add generated hosted geometry, physical/event, rescue and full-volume
normalization acceptance. Keep CT-star maps and GL638 performance claims
separate. Record the implementation and remaining measurement gates.

Validation: 216 unique core tests, including both 8192-point generated
acceptances; formatting, core/API checking and all-target clippy pass.
No clippy warnings on changed lines.

User prompt:
(continue as planned but make sure the time spent in the sampling maps is still quite significantly less than the actual GL638 all-orientation integrand, i.e. it's not crucial to optimize the runtime of the sampling, except if it is somehow comparable to the integrand time; it should be like 10% at the very most, once below that then no need to optimize further).
