chore(deps): update pnpm to 11.21.0

[escapedcat]

What

Bumps the pinned pnpm from 10.11.0 (May 2025) to the current latest, 11.21.0. Was stacked on #1246 (now merged); rebased onto main.

• packageManager: pnpm@11.21.0 — stays an exact pin (Netlify's Corepack provisioning rejects ranges, and Corepack must not see pnpm 11's new devEngines field)
• pnpm-workspace.yaml: pnpm 11 removed onlyBuiltDependencies; migrated to the new allowBuilds map. es5-ext is explicitly denied — its postinstall was already silently ignored under the old allowlist, this just makes it visible
• engines.node: >=22.13 (pnpm 11's own minimum; it's pure ESM now)
• .mise.toml: pnpm = "11"

No lockfile changes: this repo has none of the constructs (patches, peer-dedupe suffixes, config deps) that trigger pnpm 11's lockfile rewrite. Verified the lockfile stays byte-identical across repeated pnpm 11 installs (the open lockfile-churn bug pnpm/pnpm#11859 does not bite here), and pnpm install --frozen-lockfile — the CI path — passes.

Verified locally under 11.21.0

• pnpm install --frozen-lockfile ✓
• pnpm run format / lint / check (0 errors) ✓
• pnpm run test --run — 584/584 ✓
• pnpm run build (Vite + Netlify adapter) ✓

Behavior changes to be aware of (pnpm 11 defaults)

• minimumReleaseAge = 24h: pnpm refuses to resolve package versions published less than a day ago (supply-chain protection). Dependabot PRs that bump to a just-released version will fail CI until the release ages ~1 day — rerun or wait. Can be relaxed per-package via minimumReleaseAgeExclude if it gets annoying.\n- verifyDepsBeforeRun = install: pnpm run … auto-verifies node_modules against the lockfile first (may touch the network).\n- Devs need Node ≥ 22.13; any pnpm ≥ 10 on PATH self-switches to 11.21.0 via the pin. Anyone still on Corepack needs ≥ 0.34.5 (bundled in Node 22.22.1+ / 24.12+) — older Corepacks hardcode a .cjs bin path pnpm 11 no longer ships.

Netlify

Netlify installs pnpm via Corepack from the site's pinned Node. pnpm 11 needs Corepack ≥ 0.34.5 (Node 22.22.1+ / 24.12+). The deploy preview on this PR is the authoritative test — if it fails at dependency provisioning with Cannot find module …/bin/pnpm.cjs, the site's Node pin is too old and needs a bump (e.g. NODE_VERSION). Please also click through the preview (SSR pages) before merging, since a green build alone doesn't exercise the SSR function.

For later: pnpm 11 is the last major that works on Netlify's current provisioning — pnpm 12 (in RC) ships a native binary Corepack cannot run at all.

📝 Walkthrough

Walkthrough

The project updates Node.js and pnpm requirements, documents pnpm installation options, configures Netlify’s Node.js version, and changes dependency build-script permissions.

Changes

Toolchain and Build Configuration

Layer / File(s)	Summary
Toolchain version contract .mise.toml, package.json	The project pins pnpm 11, declares pnpm 11.21.0, and requires Node.js 22.13 or newer.
Setup and deployment configuration README.md, netlify.toml	The setup instructions describe standalone pnpm installation and mise install. Netlify specifies Node.js 22 and documents the Corepack requirement for pnpm 11.
Dependency build permissions pnpm-workspace.yaml	Build scripts are disabled for es5-ext and enabled for esbuild.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to eab20

The pnpm upgrade and related configuration changes have passed the supplied install, lint, type, test, and build checks; no actionable merge-blocking risk remains beyond normal Netlify preview validation.

In `@README.md`:
- Line 42: Update the README setup note to state the exact requirement “Node.js
>=22.13” instead of the broader “Node 22 LTS,” keeping the existing mise and
pnpm guidance unchanged.
- Around line 9-10: Update the README bootstrap prerequisites to require pnpm 10
or newer, directing users with an unavailable or older pnpm version to mise
install or the standalone installation methods. Replace the “Node 22 LTS”
wording with “Node.js 22.13 or newer” to match the project requirement.
