test: port the xmod same-leaf collision carriers to corpus fixtures
752_modparam_callee.c -> r752_modparam_xmod_variadic_vs_scalar,
r752_modparam_variadic_no_collision (run; alpha/beta module dirs)
784_xmod_alias_struct_collide_run.c -> r784_xmod_alias_struct_collide
(run-exit 42), r784_xmod_alias_struct_symmetric (21),
r784_xmod_alias_control (30) (sa/sb module dirs)
793_xmod_struct_argpush_collide_run.c -> r793_xmod_argpush_
{recvpush_t16 107, fieldread_t16 107, combined_t16 114,
recvpush_t12 6} (m1/m2 module dirs)
797_xmod_struct_field_layout_collide_run.c -> r797_xmod_layout_
{ptrread_t16 107, letcopy_t16 107, addrptr_pq 10, addrval_pq 10,
ptrwrite_t16 109, valwrite_t16 109} (m1/m2) + r797_nestfill_box (66)
r770-style sibling module dirs express the trees; the fixture corpus
runs both drivers natively (784's wwstage-build-only leg upgrades to
build+run) and test-data-byteid owns each carrier's aggregated per-
package .s compare (letcopy_t16's real discriminator). All 16 probed
green on both stages including per-package byte identity.
