openai/gpt-5.2-chat → A (50:1)

Side A introduces a full `durable` workspace crate (RocksDB-backed `DurableMap`/`DurableVec` with tests, examples, and docs), adds an `EntityStore` to offload raw JSON from memory to disk, and replaces bulk `load_all` with streaming `replay` to reduce startup RAM—substantial architectural improvements affecting persistence and memory usage across server modules. Side B only removes minor HTML text and tweaks CSS gradient directions, providing cosmetic changes with no structural impact.
