CLI build and tests fail when the repo is cloned to a path containing spaces

Which package or tool is having this issue?

CLI

What version of that package or tool are you using?

main @ b543c6d2 (@shopify/cli-hydrogen 13.0.4)

Steps to Reproduce

Clone the repo into a directory whose path contains a space, then build:

git clone https://github.com/Shopify/hydrogen.git "/tmp/Open Source/hydrogen"
cd "/tmp/Open Source/hydrogen"
pnpm install
pnpm --dir packages/cli build

Expected Behavior

The build succeeds, the same as it does from a path without spaces.

Actual Behavior

The build fails:

Error: Trying to use skeleton source dir outside of Hydrogen monorepo.
    at getSkeletonSourceDir (packages/cli/tsup.config.bundled_*.mjs:36:11)
    at Object.onSuccess (packages/cli/tsup.config.bundled_*.mjs:166:18)

pnpm --dir packages/cli test fails as well, with 11 failed test files and 39 failed tests on the same checkout.

Cause is in packages/cli/src/lib/build.ts:

const monorepoPackagesPath = new URL('../../..', import.meta.url).pathname;

URL.pathname is percent-encoded, so a checkout at /Users/me/Open Source/hydrogen yields /Users/me/Open%20Source/hydrogen/packages/. That path does not exist on disk, so the existsSync check for templates/skeleton fails, isHydrogenMonorepo is false, and getSkeletonSourceDir() throws.

The error message points at the monorepo layout rather than the directory name, so the actual cause is not obvious. The fix is to decode the pathname before use.

Confirmed on the same machine by toggling only that one expression:

Note that packages/hydrogen/src/vite/plugin.ts uses the same new URL(...).pathname pattern, but is not affected, because it only checks endsWith('/packages/') and any encoded segment appears earlier in the path.

This only affects working in the monorepo. Installed npm packages are unaffected, since isHydrogenMonorepo is false there either way.

I have a fix ready and will open a PR shortly.

Start in packages/cli/src/lib/build.ts and inspect how the monorepo package path is derived from import.meta.url. Reproduce with a checkout under a path containing spaces, then run pnpm --dir packages/cli build and pnpm --dir packages/cli test. Done means the build succeeds and the CLI tests pass from the spaced path.
