fix(client-effect): lint auto-fixes from slice #46

ESLint --fix output on packages/client/src/client-effect.ts and the
companion test file: drop redundant type assertion + default-value type
arguments; reorder imports to match import/order rule; replace
Array.from(collected) with spread. Pure mechanical fixups; no behavior
change. Tests still green.
