build: Update pnpm and Node baseline (#1117)

Move the workspace to pnpm 11.8.0 and Node 22.13+ so the package-manager
runtime requirement matches the repository baseline. pnpm 11 no longer
reads the root package.json pnpm block, so the workspace overrides and
build-script policy now live in pnpm-workspace.yaml.

CI workflows now use Node 22, and the setup/testing docs advertise the
same Node 22.13+ prerequisite. The lockfile is unchanged; this is a
tooling baseline and configuration migration rather than a dependency
version refresh.

Validation: pnpm install --lockfile-only, pnpm run tsc, pnpm run lint,
pnpm run test, pnpm run docs:check.
