In `@global/commands/src/listGlobalPackages.ts`:
- Around line 45-48: The early return for the empty dependencies case returns an
object missing the dependencies field; change it so the returned JSON object
matches the normal renderer schema by including an empty dependencies array. In
the branch where reportAs === 'json' and dependencies.length === 0 (refer to the
dependencies variable, reportAs check, and globalPkgDir), return an object with
path: globalPkgDir, private: true and dependencies: [] serialized with
JSON.stringify so downstream consumers can safely read result[0].dependencies.

In `@deps/inspection/commands/src/listing/list.ts`:
- Around line 119-137: When depth>0, don't let the package-name filtering in
params cause findGlobalInstallDirs(...) to return no installs; call
findGlobalInstallDirs in a way that ignores the package filter (e.g. pass params
stripped of search filters or call the overload that only uses
opts.globalPkgDir) so that if installDirs.length === 1 we still take the
single-install fast path and call render([installDirs[0]], params, {...}) as
before; this lets listForPackages()/render perform the actual dependency
filtering instead of falling back to listGlobalPackages(). Update the call site
that currently uses findGlobalInstallDirs(opts.globalPkgDir, params) to use an
unfiltered params variant (while keeping the original params when invoking
render) and add/update a test covering `@pnpm.e2e/dep-of-pkg-with-1-dep` for pnpm
ls -g <transitive-dep> --depth=1.

In `@pnpm/test/install/global.ts`:
- Around line 490-504: The test 'global ls --parseable outputs paths' currently
parses stdout using split('\n'), which leaves trailing '\r' on Windows and
breaks the endsWith(...) assertion; change the parsing after execPnpmSync (the
stdout returned by execPnpmSync in this test) to split using a CRLF-safe regex
and normalize each line (e.g., split with /\r?\n/, then map each line through
trim() and filter out empty strings) so the subsequent expect(lines.some(...))
check is reliable across platforms.

Nitpick comments:
In `@deps/inspection/commands/src/listing/list.ts`:
- Around line 118-157: Call findGlobalInstallDirs(opts.globalPkgDir, []) once
and reuse that result instead of invoking it twice; compute allInstallDirs from
that cached snapshot, then derive matchingInstallDirs by filtering that cached
list against params (or by calling a cheap in-memory matcher using params) so
the filesystem is scanned only once; update references to allInstallDirs and
matchingInstallDirs in the branch around render(...) and the PnpmError throw to
use the cached data.
