refactor: Enforce Rayon parallelism and fix merge_layer concurrency

Browse Source 
Updated memory guidelines and feedback docs to explicitly classify intra-partition phases as parallel, correcting prior assumptions of sequential execution. Refactored merge_layer.rs to wrap column builders in Arc<Mutex<ColBuilder>> and use Arc::try_unwrap for safe concurrent access, eliminating race conditions and preventing double-closes during pass2.
