feat(scripts): add check:type running real tsc per package

Each package gets check:type = `tsc --noEmit` (under its own tsconfig); root
check:type = `vp run -r check:type` fans out across the workspace. Unlike vp's
tsgolint-based type-aware path, this is the standard TypeScript compiler, so it
honors each tsconfig's real project semantics.

Additive only here — vp lint still carries typeCheck; the switch-over and ready
rewiring land in the next commit. Note: testing and runtime-tests resolve
@vue-tui/runtime types from its built dist, so check:type requires a prior
build.
