Pass the CCtx compressed-block-state pointer slot and CDict source state
through the attach/copy bridges, then perform the final state copy in Rust
after reset has established the destination. Remove the redundant C memcpy
adapters while preserving dictionary attach/copy ordering and null/error
behavior.
Add focused tests for copied repcodes and entropy repeat state.
