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

Side B implements a real feature (Reddit OAuth linking, UUID-as-canonical-identity refactor) with new server logic, storage helpers, event handling, and updated tests/mocks that materially change and extend system behavior. Side A is a substantial but purely cosmetic CLI/docs restructuring (renaming ingest to forum post, reshaping subcommands, updating DSL text) with no new functionality or bugfix, aside from removing an XML-escaping call which risks a minor regression.
