Zoltan Kochan ec7cf70853 fix(dlx): shorten dlx cache path to avoid Windows MAX_PATH failures (#12605)
The dlx cache path is <cacheDir>/dlx/<key>/<prepare>/node_modules/.pnpm/
<pkgId>/node_modules/<pkg>. The <key> (64-char sha256 hex) and <prepare>
(<time>-<pid> in hex) segments are dlx overhead on top of pnpm's already-
deep virtual-store layout. For a transitive dep with a long name this tips
the package directory over Windows' MAX_PATH (260) — measured at 259 chars
for @pnpm.e2e/pre-and-postinstall-scripts-example in the dlx e2e test. A
lifecycle script then runs with that directory as its cwd, and CreateProcess
fails to resolve an over-length cwd, which Node surfaces as the confusing
"spawn C:\Windows\system32\cmd.exe ENOENT". Flaky rather than constant
because the <prepare> and temp-dir segments vary in length, straddling 260.

Shorten both dlx-specific segments:
- cache key: createShortHash (32 hex, 128 bits) instead of createHexHash
  (64). pacquet already truncated to 32, so this also restores parity.
- prepare dir: encode time and pid in base36 instead of hex.
