~anthropic/claude-sonnet-latest → A (6:4)

A fixes a genuine bug (the external garden root listing was always empty) and cleanly refactors the GitHub resolver into a structured, tested module with real UI/test coverage, all without new heavy dependencies. B vendors an entire third-party 'durable' RocksDB crate wholesale (README, docs, LICENSE, examples, benchmarks, its own Cargo.lock) just to back a simple string->string entity cache, adding a large, mostly irrelevant dependency footprint (rocksdb/bindgen/clang) disproportionate to the actual need, even though the underlying entity_store/streaming-replay idea has some merit.
