refactor(scripts): fold check:fixtures into check:type

A single top-level `vp run check:type` should fan out (-r) and fully type-check
every package, fixtures included — no separate top-level check:fixtures step.
runtime-tests' check:type now runs its main tsc then its fixtures tsc
(check:fixtures stays as a runnable sub-script). Drop the root check:fixtures
entry and its standalone step in ready.
