Round-14 rebase onto main (7 commits, mostly the Expo SDK 57 upgrade
plus the mobile glass restore and codex app-server buffering fix). The
mobile composer merged main's restored glass chrome onto the v2 body,
and the lockfile is regenerated from main's SDK-57 lock with the
branch's extra dependencies installed on top.
