Mini Codex V2 becomes the production path

June 3's update makes Mini Codex V2 the default production surface, adds live agent-loop and event replay support, removes legacy Mini Codex source paths, improves production UX, and brings Avatar Studio into V2.

Mini Codex V2 save evidence now covers Asset Studio, Game Studio, Studio Docs, event replay, default routing readiness, and final Stage 12 verification.
Stage 13 removes legacy host surfaces and preload methods, routes V2 submits through host tools, marks proven legacy gates deleted, and verifies the V2-only routing path.
Workbench transcript UI, shell styling, and frame pieces moved into shared V2-owned components so product surfaces can reuse the familiar layout without reviving legacy behavior.
The V2 agent loop now drives production flows with run status, transcript updates, host apply coordination, subject production tools, and clearer pre-work messages.
Production UX now shows stronger pending/apply state, progress copy, host evidence, and transcript treatment while avoiding legacy patch-card fallback.
Avatar Studio now has V2 production contracts, a V2 host entry, active avatar boundary coverage, and virtual-file production support.
Stage 15 deletes remaining legacy Mini Codex source paths and aligns docs, Electron bridge ownership, debug summaries, workflow tests, and cleanup contracts around V2-only behavior.
