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

Side A adds a self-contained, well-tested dev tool (offline compiler/linter) with clear docs and no risk to production code paths, reusing existing server logic cleanly via a new offline.rs module. Side B is a large, invasive refactor (scope->tree, settlement->journal rename, ItemId overhaul) that touches many core files simultaneously with a vague 'reconfigure' message, increasing risk despite adding real tree/breadcrumb functionality; its scope creep and rename churn (settlement->journal) reduce clarity of lasting value compared to A's precise, additive tool.
