  1. fix data race in resetted_jump_problem, decorrelate jump/noise seeds 

    Remove dead randexp!(_jump_prob.rng, ...) blocks from resetted_jump_problem
and reset_jump_problem! that caused a data race when called from multiple
threads via EnsembleThreads. The jump_u values they wrote were unconditionally
overwritten by VR_FRMEventCallback's initialize method.

Add _derive_jump_seed to decorrelate the jump aggregator's seed from the
noise process seed when StochasticDiffEq passes the same seed to both.

Add test/ensemble_problems.jl covering serial stream uniqueness, sequential
solve independence, threaded completion (no data race), seed-based stream
independence, and VR_FRM jump_u threshold uniqueness.

  2. use hash + Xoshiro for seed derivation, add salt constant 

    Strengthens _derive_jump_seed by hashing the input seed with a fixed
salt before passing through Xoshiro. This ensures decorrelation from
the caller's seed regardless of the JumpProblem's stored RNG type.

  4. fix CI: update jump_u test to use integrator, remove stale randexp! i… 

    …mport

The variable_rate.jl test was checking prob.u0.jump_u, but VR_FRM's
callback initialize sets integrator.u.jump_u (a copy). Updated the test
to use init() and check the integrator's jump_u values directly.

Also removed the stale randexp! import that was flagged by ExplicitImports.
