openai/gpt-5.2-chat → B (3:1)

Commit B introduces a new durable storage subsystem (a full RocksDB-backed workspace crate), integrates it into the server for off-heap entity storage, and refactors event log replay to stream line-by-line—significantly improving architecture, scalability, and startup memory behavior. It spans many files, adds substantial functionality (new crate, APIs, examples, docs), and changes core persistence paths. Commit A is a solid feature/refactor (GitHub resolver modularization, rich cards, external index fix, tests, CSS), but its impact is primarily at the application/UI and resolver layer. B represents a deeper infrastructural enhancement with broader long-term impact.
