Allow LinearSolve v4#1002

Conversation
LinearSolve v4.0.0 adds batched (matrix) right-hand side support (SciML/LinearSolve.jl#1072). NonlinearSolve is functionally unaffected — the one production solve site in NonlinearSolveBase passes a flattened vector — so this only widens compat to include v4 and bumps affected subpackage patch versions. (NonlinearSolveBase already at 2.31.4.) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Widens `LinearSolve` compat to include v4 and bumps affected subpackage patch versions.
Context
LinearSolve v4.0.0 (SciML/LinearSolve.jl#1072) adds batched (matrix) right-hand side support. The only breaking aspects are (1) the
u0shape for a matrixbchanges from a flattened length-nvector ton×k, and (2) matrix-b+ iterative solvers now error atinit.The #1072 downstream audit found NonlinearSolve functionally unaffected: the one production solve site (in NonlinearSolveBase) passes a flattened vector. So this PR is compat-only.
Changes
LinearSolve = "3.48"→"3.48, 4"— top-level, NonlinearSolveBase,test/gpuLinearSolve = "2.36.1, 3"→"2.36.1, 3, 4"— NonlinearSolveFirstOrder, NonlinearSolveQuasiNewtonLinearSolve = "2, 3"→"2, 3, 4"—docs2.31.4(already one patch ahead of the registered2.31.3); its compat change rides that pending version. Test/docs envs not bumped.CI here will go green once LinearSolve v4.0.0 finishes propagating into the General registry.
