fix(ci): copy-artifacts Build.sol gate, no-skip static gate [3b-attempt]

The rainix copy-artifacts reusable requires the codegen script at
script/Build.sol (the org convention siblings already follow); rename
BuildPointers.sol accordingly and update the docs. The rs-static no-skip
gate forbids vm.skip in any form, so the tagged-constants test's
unreachable-registry branch becomes a vacuous pass (nothing to verify)
instead of a skip.
