refactor: move type-checking from vp lint to tsc-based check:type

Set lint.options.typeCheck=false so vp lint/check no longer runs the
tsgolint full type-check (typeAware stays on, keeping type-aware lint rules).
Type-checking is now owned by check:type, which runs the real tsc and honors
each tsconfig's project semantics — unlike tsgolint, which ignored tsconfig
exclude/nested configs.

Wire check:type into ready after build (it needs the built dist for
cross-package type resolution): fmt, lint, build, check:type, check:fixtures,
test.

Verified: with typeCheck off, vp lint no longer reports a TS2322 type error
(but keeps its type-aware warnings); check:type catches it via tsc.
