• Build: publish the optimised JS build, make build.js robust, shrink the package #34: build:compiler uses moon build --target js --release (526 KB instead of 669 KB, output of all 13 examples identical to the debug build); scripts/build.ts copies the release artifact
• Language decision: expression-bodied fn / getter does not return its value #60 decision: keep the semantics (changing them is breaking, major only); the linter warns on named fn/getter expression bodies without return (rule expression-body-no-return, 1 test); RFC note in section 7

Tests: linter 13/13, wrapper 25/25, typecheck/ESLint/Prettier clean.
