ADR-0005 in-process tool runtime — 6 tools (catalog 2 + tracker 2 + habit 2), ToolDispatcher with JSON-schema validation + modal ConfirmGate for destructive ops, multi-turn LlmChatSession abstraction wired to flutter_gemma 0.16.5 (ToolChoice.auto), ChatSessionController with MAX_TURNS=4 safety + 8-turn history hint, ChatScreen entry behind AI opt-in. R3/R7/R8 enforced inside handlers. 41 new tests (envelope, catalog/tracker/habit tools, dispatcher, controller loop) — 151 total passing. Refs #260
