Adds root scripts so build, test and typecheck run from the workspace root:
- root package.json gains scripts: build (pnpm -r run build), test
(node --test on tests/**/*.test.mjs), typecheck (pnpm -r run typecheck)
- every workspace package (apps/server, packages/core,
extensions/example) gains build (tsc -p tsconfig.json) and typecheck
(tsc -p tsconfig.json --noEmit) scripts
- typescript 6.0.3 pinned as an exact root devDependency so the commands
run from a clean checkout; lockfile regenerated with pnpm 11.23.0
Verified from a clean state: pnpm install --frozen-lockfile passes,
pnpm build emits dist for all 3 packages, pnpm typecheck passes for all 3,
pnpm test runs tests/architecture-import.test.mjs 10/10 green, and CI's
pnpm -r list --depth -1 still lists all 4 workspace projects.
