In crs: Categorical Regression Splines

crs 0.15-44

• Added the final package-author native NOMAD C API (crs_nomad_solve) with C and R callback modes, explicit option arrays, generated starts, multistart support, budget handling, mesh-size array options, interrupt handling, and deterministic seed behavior for downstream packages.
• Exposed NOMAD native cache counters from snomadr() (cache.hits, cache.size, callback.evaluations, and total.evaluations) so downstream callers can distinguish true R callback evaluations from points satisfied by NOMAD's cache without changing optimizer behavior.
• Hardened native NOMAD API contracts by rejecting cache-off native solves, mirroring infinite objective handling, documenting main-thread affinity for R callback routes, and tightening named-list validation in native helpers.
