* fix(dlx): make failed-install cache cleanup best-effort
On Windows, `pnpm dlx` could fail with a spurious "EBUSY: resource busy
or locked, rmdir" error. When an install into the dlx cache failed, the
catch block removed the partially-populated prepare dir with
`fs.promises.rm(cachedDir, { recursive: true, force: true })`. That call
has no retries, so it died on the same lingering Windows handle (a
just-run install script's child process, or antivirus scanning freshly
written files) and threw EBUSY — which then replaced and masked the
original install error.
Make the cleanup best-effort: swallow its failure so the original error
always surfaces, and add `maxRetries`/`retryDelay` so the removal itself
succeeds once the transient lock clears. A leftover prepare dir is
harmless — it has a unique name and findCache only trusts the `pkg`
symlink.
The pacquet port already removes the prepare dir best-effort (`let _ =
fs::remove_dir_all(...)`) and returns the original error, so the
user-visible behavior already matches; only the (non-observable) retry
is absent there.
* fix(dlx): log dlx cache cleanup failures instead of swallowing them
Catch the best-effort cache cleanup with a narrow handler that logs the
failure via logger.warn (mirroring tryRemovePkg in modules-cleaner's
prune) instead of a blanket `.catch(() => {})`. The original install
error is still the one rethrown, so cleanup failures stay visible without
ever masking the real cause.

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!

why it works fine with the Node.js ecosystem, read this small article: Flat node_modules is not the only way.
