~anthropic/claude-sonnet-latest → B (65:35)

B performs a substantive refactor: moves path/URL logic into a shared `slug-types::paths` module, introduces well-typed newtypes (GardenItemUrl, ForumThreadUrl, TildeOntologyPath) that are correct-by-construction and used consistently across RPC/validation code, improving type safety and removing duplicated string-based helpers. A's commit removes an unrelated demo-counter feature and adds a plausible but half-baked async settlement/batching worker with caching, which is useful but smaller in scope, less tested, and mixes unrelated concerns (feature removal + new architecture) in one commit.
