Upgrade the workspace from pnpm 11.21.0 to 12.18.0. Regenerate the lockfile to record pnpm's platform binaries and update the Next.js migration guides. The workspace dependency document is byte-for-byte identical.
This follows the exploratory draft in #8612. Codex authored this change and PR description.
Validation
CI=1 pnpm install --frozen-lockfile passed for all 314 workspace projects on Node 26.12.1.
pnpm format and the Nx build, unit tests, type checks, and lint for @tanstack/history passed.
test:docs reported two pre-existing broken example links in the React Start production checklist and TanStack Query guide.

This change is docs/CI/dev-only (no release).
Summary by CodeRabbit
Documentation
Updated the React migration guide and example setup instructions to require pnpm 12.
Updated the project’s package manager requirement to pnpm 12.18.0 or later. The minimum Node.js version remains 24.
These requirements are consistent across the project guidance and package setup, helping ensure developers use a supported pnpm version when following the instructions.
Chores
Updated build automation and benchmark commands to use the configured package manager.
Merging this PR will not cause a version bump for any packages. If these changes should not result in a new version, you're good to go. If these changes should result in a version bump, you need to add a changeset.

Walkthrough
The package metadata and React migration instructions now require pnpm 12. The compiler-platforms workflow uses pnpm/action-setup v6.1.1. Bundle-size benchmark scripts invoke the configured package-manager executable, or pnpm, with the exec subcommand. The documented Node.js minimum remains 24.
Changes: pnpm requirement update
Layer / File(s)
Summary
Update pnpm version requirements package.json, docs/start/framework/react/migrate-from-next-js.md, examples/react/start-next-migration/README.md, .github/workflows/compiler-platforms.yml
The package manager version and minimum pnpm engine version change to 12.18.0. The migration guide and example instructions change from pnpm 11 to pnpm 12. The workflow updates pnpm/action-setup from v6.0.7 to v6.1.1.
Build, package-build, and test commands use npm_execpath when set, or pnpm otherwise, and invoke exec. The build test checks the full command argument list.
No actionable merge-blocking risk is established for the pnpm upgrade or benchmark commands. The change is ready to merge after normal checks.

Explanation
The title "chore(pnpm): upgrade to pnpm 12" matches the main change. The PR upgrades the workspace package manager from pnpm 11.21.0 to pnpm 12.18.0. The supporting changes update the engine requirement, the lockfile, the pnpm/action-setup CI action, the benchmark scripts that invoke pnpm, and the docs that name the pnpm version. The title is short, specific, and uses a conventional commit prefix.

Explanation
The description covers the required template sections. The Changes section states the pnpm upgrade and its motivation. The checklist items are filled in, and the Release Impact section marks the change as docs/CI/dev-only. It also discloses AI authorship, as the template requires. The description includes a validation section that reports test results.
Resolution
Check the unchecked item: "I fully understand the code in this pull request, including any code generated with AI assistance." The author must confirm this before merge, because the description states that Codex wrote the change.

Handle native pnpm executables in the benchmark runner
When npm_execpath points to a native pnpm executable, --test-projects passes it to Node as a script. The test step can fail before Nx runs, so measurement is skipped. Fix this invocation separately from build.mjs: execute native pnpm directly, while retaining Node for JavaScript pnpm entrypoints.

Handle native pnpm executables in the benchmark wrapper.
With pnpm 12, npm_execpath can point to a native executable. build.mjs passes that path to Node as a script, so the PR benchmark can fail before measurement. This also blocks its dependent comment job and can block main-history publication.
Launch native pnpm executables directly while retaining support for JavaScript pnpm entrypoints.

Install a Windows-compatible pnpm 12 executable
When the Windows runner uses the action’s pnpm 11 bootstrap, self-update skips pnpm 12’s install script and leaves an extensionless shell placeholder. Nx then invokes that placeholder through the Windows shell, so unit tasks can fail and block the production-build step.
Install pnpm 12 with its lifecycle scripts enabled and expose its native Windows executable to Nx.

Update the pnpm setup associated with packageManager and engines.pnpm so Windows
installs pnpm 12 with lifecycle scripts enabled and Nx resolves its native
Windows executable. Avoid relying on the pnpm 11 self-update path that leaves an
extensionless shell placeholder.

Handle native pnpm in the benchmark runner.
When pnpm 12 sets npm_execpath to its native executable, run.mjs passes that executable to Node as a script. The test step fails, so the documented --test-projects command stops before measurement. Update this invocation as well as the separate build.mjs wrapper.

Failed pre-merge checks:
- Description check:
Check the unchecked item: "I fully understand the code in this pull request,
including any code generated with AI assistance." The author must confirm this
before merge, because the description states that Codex wrote the change. The
description does not mention the benchmark script changes (build.mjs, run.mjs,
measure.mjs, build.test.mjs) or the pnpm/action-setup CI action bump. Add a
short note about these changes so reviewers know the full scope.
- Docstring Coverage:
Write docstrings for the functions missing them to satisfy the coverage
threshold.

Takes main's pnpm 12 upgrade (#8912), the RSC dependency bump (#8919) and
the react-start HMR e2e fix (#8913).
The lockfile is main's, regenerated with pnpm 12 for the slice's packages.
pnpm 12 merges a version a package names directly into the other
packages' ranges, so two ranges of the slice are set to the versions main
already resolves, to leave every other package's resolution as on main:
the harness's `esbuild` (^0.28.1; ^0.28.2 added a second esbuild and moved
webpack's peer variant) and router-plugin's `@babel/preset-typescript`
(7.27.1; ^7.28.5 moved esbuild-plugin-solid's preset and the preset's own
helpers). The only change left outside the slice's packages is the css-modules
e2e apps' sass bump.

🎯 Changes
Upgrade the workspace from pnpm 11.21.0 to 12.18.0. Regenerate the lockfile to record pnpm's platform binaries and update the Next.js migration guides. The workspace dependency document is byte-for-byte identical.
This follows the exploratory draft in #8612. Codex authored this change and PR description.
