Migrate pnpm config to v11

[rtbenfield]

Updates the repository pnpm configuration for pnpm v11 compatibility after the package-manager pin moved from v10 to v11.

Changes

• Package manager pins: Updates the root project and standalone example projects to use pnpm@11.6.0 so local and example installs do not fall back to pnpm 10.
• Node runtime pin: Updates .node-version to the latest Node 22 release and raises the root development engine floor to >=22.13.0, matching pnpm v11's runtime requirement.
• Example pnpm config: Moves the Next smoke postcss override out of the removed package.json#pnpm config field and into examples/next-smoke/pnpm-workspace.yaml, where pnpm v11 reads project configuration. The 8.5.10 pin preserves the existing lockfile resolution, so this migration does not downgrade the example from a newer PostCSS release.
• Build approvals: Adds allowBuilds.esbuild: true to the root and standalone example workspaces so esbuild install scripts are explicitly approved under pnpm v11's build policy.

Why

pnpm v11 no longer reads pnpm-specific settings from the pnpm field in package.json, requires Node >=22.13, and uses allowBuilds for dependency build-script approvals. Keeping these settings in workspace config preserves the existing install behavior while making the repo compatible with v11.

Walkthrough

This PR upgrades pnpm from version 10.30.0 to 11.6.0 across the workspace by updating the packageManager field in the root package.json and two example project package.json files. Concurrently, the PR consolidates a postcss dependency override from the examples/next-smoke/package.json into the examples/next-smoke/pnpm-workspace.yaml workspace configuration, ensuring the dependency constraint is maintained after the pnpm upgrade.

postcss to 8.5.10 (e.g., compatibility with Next.js/other deps, security fixes,
or reproducible installs) and mention that pnpm-lock.yaml currently resolves
postcss to 8.5.10 (so this is not a downgrade from 8.5.15).
