Version: CURRENT_PROJECT_VERSION 130 -> 131 (project.yml, AGENTS.md, READMEs, docs/llms.txt). fix(flow): host-app identification now compiles in every build configuration (Debug, TestFlight, Release). The arbiter probe and HostAppIdentity were DEBUG-only, so TestFlight/App Store builds never knew the host bundle id and could not auto-return after a startflow handoff. Debug-only logging and the Home test card are unchanged. Also includes the pending work in the tree: - Home: single account/setup card surface (HomeAccountSurfacePolicy/Views) - Wide screens: voice key row and centred mic placement, iPhone Duo layout - Keyboard: clipboard skill ranking and AI skill layout updates - Debug: account session handoff to the Simulator (+ import script) - Docs: portfolio assets, privacy policy URL, site/README refresh
