Chunk 17.0

## Summary In this chunk, the assistant completed the memory manager implementation by fixing the remaining loose ends. The third `extract_and_cache_pce_from_c1` call in `cuzk-bench/src/main.rs` was updated to accept the new `PceCache` parameter, and the `SrsManager::new` call in the same function was converted from the old `(PathBuf, u64)` signature to the new `(PathBuf, Arc<MemoryBudget>)` signature. Two compile errors were resolved: adding `mut` to the `synth_job` binding in `engine.rs` to allow `.take()` on the reservation, and removing the `'static` lifetime requirement from `synthesize_with_pce`'s `pce` parameter (which was a leftover from the old `OnceLock` static pattern). All unused imports were cleaned up, and stale references to the removed `get_pce` API were confirmed to be zero across the codebase. The implementation was then validated through multiple stages. `cargo check` passed with zero errors, all 8 memory module tests and all 7 config tests passed, and a real-world `pce-bench` run with 32 GiB PoRep data on a 754 GiB RAM / RTX 5070 Ti machine successfully extracted a 25.7 GiB PCE and validated correctness across all 10 circuits (130M constraints each). The changes were committed with a descriptive message. Finally, the assistant investigated the target deployment machine (141.0.85.211, 755 GiB RAM, RTX 5090, 64 cores) and found that while curio is running, cuzk is not currently active, and the existing config at `/tmp/cuzk-run-config.toml` still uses the deprecated `preload` and `partition_workers` fields that need updating for the new memory manager. **Themes**: Final integration fixes and validation of the budget-based memory manager; real-world correctness testing with production-scale data; preparation for deployment by assessing the target environment and its configuration gaps.
