V46 Gate 7: Local interface comprehension rehearsal

Add package-backed V46LocalInterfaceComprehensionRehearsal with deterministic source-safe local rehearsal metadata for docs, product routes, API/MCP, ChatGPT App, Bitcode Chat, proof telemetry, and repair readback.

Wire generator, checker, exports, focused protocol tests, Gate Quality and Canon Quality workflows, regenerated V46 artifacts, and spec/roadmap/README documentation for Gate 7 closure.
