Fixes #29. rcond and condest already worked but weren't exported, so using KLU; rcond(klu(A)) threw UndefVarError. This PR exports them, along with rgrowth, which is part of the same family, and adds all three to the API list in the docs.

None of the three names exists in Base, LinearAlgebra or SparseArrays on Julia 1.13, and unqualified use works alongside using LinearAlgebra on 1.10. Other packages weren't checked for clashes. LinearAlgebra.cond isn't extended, because it defaults to the 2-norm and condest estimates the 1-norm.

Testing

The new tests cover real and complex values with Int32 and Int64 indices, and compare results against independent calculations from the factors and dense matrices. They also cover refactorization, computing the factorization on demand, and singular matrices. The full suite passes locally on macOS with Julia 1.13 at -t 2.

Review fixes in 2e48bd5. rgrowth made a singular factorization report issuccess(F) == true, because klu_rgrowth resets Common->status. The status is now restored after the call, and a test covers it. The three docstrings moved out of the @eval loop, since each function had four identical copies. The docs build now renders each one once.
