* chore(release): don't re-lint the pnpm CLI at publish time The pnpm package's `prepublishOnly` ran `compile`, which includes `eslint --fix` over the src and test files. On the macOS release runner the `import-x/no-extraneous-dependencies` allow-list for test files did not take effect, so linting reported hundreds of spurious errors and aborted the publish of the `pnpm` wrapper — the last package the release job publishes — leaving 11.13.0 unpublished. Split the artifact build out of `compile` into a new `build` script and point `prepublishOnly` at it, so publishing no longer re-lints. Lint is still run by `compile` (used for local development and `pnpm test`) and enforced by CI on every PR, so a merged, tagged release commit is already linted. `build` runs the same tsgo build, bundle, and asset-copy steps `compile` did; only the lint step is removed from the publish path. The scripts are generated by the meta-updater, so the change is made there and the generated `pnpm/package.json` is regenerated to match.

Fast, disk space efficient package manager:
- Fast. Up to 2x faster than the alternatives (see benchmark).
- Efficient. Files inside
node_modulesare linked from a single content-addressable storage. - Great for monorepos.
- Strict. A package can access only dependencies that are specified in its
package.json. - Deterministic. Has a lockfile called
pnpm-lock.yaml. - Works as a Node.js version manager. See pnpm runtime.
- Works everywhere. Supports Windows, Linux, and macOS.
- Battle-tested. Used in production by teams of all sizes since 2016.
- Experimental Rust port. Includes pacquet, an experimental port of the CLI written in Rust.
- See the full feature comparison with npm and Yarn.
To quote the Rush team:
Microsoft uses pnpm in Rush repos with hundreds of projects and hundreds of PRs per day, and we’ve found it to be very fast and reliable.

Background
pnpm uses a content-addressable filesystem to store all files from all module directories on a disk. When using npm, if you have 100 projects using lodash, you will have 100 copies of lodash on disk. With pnpm, lodash will be stored in a content-addressable storage, so:
- If you depend on different versions of lodash, only the files that differ are added to the store.
If lodash has 100 files, and a new version has a change only in one of those files,
pnpm updatewill only add 1 new file to the storage. - All the files are saved in a single place on the disk. When packages are installed, their files are linked from that single place consuming no additional disk space. Linking is performed using either hard-links or reflinks (copy-on-write).
As a result, you save gigabytes of space on your disk and you have a lot faster installations!
