chore: make CI strict — fmt diff + deny-warn - #3

Previously CI ran `moon check --warn-list=-a`, which silenced every warning including new nightly deprecations. Tightening it so that deprecation warnings become CI errors and get migrated promptly: - `moon fmt && git diff --exit-code` — enforces fmt cleanliness - `moon check --deny-warn` — warnings are errors - `moon test` — unchanged Generated with Claude Code (https://claude.com/claude-code).

Three small changes to pass the new strict CI: - moon.pkg: import `moonbitlang/core/test` so the `(it : @test.Test)` parameter in test signatures resolves (was [E0071]). - test files: turn the last `..foo()` in each DotBuilder cascade into `.foo()` — the discarded `x..f()` value is now a hard error [E0027]. - README.mbt.md: same cascade fix inside the embedded snippet. All 28 tests still pass under `moon test`. Generated with Claude Code (https://claude.com/claude-code).

Why
The existing CI workflow uses
moon check --warn-list=-a, whichsilences every warning including new nightly deprecations. This means
deprecated syntax and APIs sneak in unnoticed.
Tightening it so deprecations become CI errors and get migrated early.

main, that's the point: surfacingoutstanding deprecations. They should be fixed in follow-up PRs.
