Bumps the Next.js version used in the monorepo from 16.2.7 to 16.3.0, along with the pinned @next/env and @next/eslint-plugin-next packages.

Stacked on #17632 — review that one first.

TypeScript detection

Next.js 16.3 changes the default of experimental.useTypeScriptCli to true. In CLI mode Next looks for a typescript/bin/tsc binary instead of the compiler API at typescript/lib/typescript.js:

const typescriptCliPackage = { file: 'typescript/bin/tsc', pkg: 'typescript', exportsRestrict: true }

This repo aliases typescript to @typescript/typescript6, which only ships a tsc6 bin. getTypeScriptPackageInfo reads packageJson.bin.tsc, gets undefined, and Next reports the package as missing — then tries to run pnpm add --save-dev typescript at the workspace root, which fails:

It looks like you're trying to use TypeScript but do not have the required package(s) installed.
[ERR_PNPM_ADDING_TO_ROOT] Running this command will add the dependency to the workspace root...

Both next.config.mjs and test/next.config.mjs now set useTypeScriptCli: false so Next keeps using the compiler API, which the alias does provide.

Scope

Templates stay on 16.2.7 and are bumped separately, to keep this diff reviewable.

Testing

  • @next/env resolves at 16.3.0 from both packages/payload and test; @next/eslint-plugin-next resolves at 16.3.0 from packages/next.

Bumps the Next.js version used in the monorepo, along with the pinned
@next/env and @next/eslint-plugin-next packages.

Next.js 16.3 changes the default of experimental.useTypeScriptCli to true,
which makes Next look for a `typescript/bin/tsc` binary instead of the
compiler API. This repo aliases `typescript` to @typescript/typescript6,
which only ships a `tsc6` bin, so Next reported TypeScript as missing and
tried to install it at the workspace root. Both next.config.mjs files now
set the flag to false so Next keeps using the compiler API.

Templates stay on 16.2.7 and are bumped separately.
Nesting @Keyframes inside a style rule is invalid CSS - only conditional
group rules can nest. Next.js 16.3 ships a stricter CSS parser that rejects
the rule and drops the read-only editor styles.

Hoist the keyframes to the top level of the layer and scope its name, since
hoisting makes the name global.
The canary line renamed the HMR path at 16.2.1-canary.2, a month before
16.3.0-canary.0 existed, while the 16.2 patches were cut from a branch
without the rename. So 16.2.1-canary.26 serves /_next/hmr and 16.2.7
serves /_next/webpack-hmr. The 16.3 boundary holds for stable releases
only.
