Expose basis_matrix and plotting helpers consistently, and use max_k for FPCA/FSVD component caps. Keep deprecated generic bindings, maxK keyword compatibility, and legacy stored settings keys. Integrate the FACE, sparse FACE, smoothed basis FPCA, and FSVD additions from current main; their new code and tests use the canonical names. The new master base preserves the existing main branch.

Develop workspace dependencies recursively from sibling master checkouts, including transitive dependencies and test extras on Julia 1.10. Add the master bootstrap/test runner, naming guard, and matching CI/development instructions. Package versions and UUIDs are unchanged; historical benchmark environments/results remain frozen.

Prerequisite migration PRs: KernelSmoothing.jl #78.

Coordinated merge order: ProximalBase.jl #111 and KernelSmoothing.jl #78; then ProximalSolvers.jl #93 and FunctionalDataAnalysis.jl #32; then HighDimensionalModels.jl #95; then CovarianceSelection.jl #33; finally DiffPrecTest.jl #12 and FunctionalGraphicalModels.jl #11.

Validation: all four Julia/platform test jobs, documentation, and both Codecov checks pass. Plotting-wrapper tests exercise the real missing-backend boundary and argument forwarding.
