Add `GpuProverBuilder::with_setup_cache_path`. On first run the prover computes the per-level setups as before and dumps them to the given path; on later runs the cache is loaded with the upstream `UnrolledProver::new_with_cache` constructor and the multi-minute setup compute is skipped. The caller is responsible for keying the cache path on a binary fingerprint — stale caches surface as proving-time failures, not load errors. Bumps the pinned zksync-airbender rev to f1e26aa5 to pick up the new constructor.

- Add `RealVerifierBuilder::with_vk_cache_path` so callers can persist the multi-minute VK derivation across process restarts (mirrors the GPU prover's setup cache). - Add `RealVerifierBuilder::with_setup_cache_path` plus `vk::unified_vk_from_setup_cache` so a verifier can derive its `RecursionUnified` VK directly from a pre-existing prover setup cache, no compute. Cuts the verifier startup to a file read. - Switch `create_unrolled_prover` to a load-only semantic: when a setup cache path is provided, the file MUST exist; missing-file is now surfaced as `HostError::SetupCacheNotFound` instead of being silently re-computed and written. Server deployments expect caches to be pre-generated. - Add the inverse `From<SecurityModel> for SecurityLevel` conversion that the new VK derivation needs. Updates the docs on `with_setup_cache_path` to reflect the new contract.
