`pnpm cache list-registries` printed the mirror directory name where `pnpm cache view` printed a decoded registry URL, so the two disagreed about what a registry is called and the listing gave no way to tell a live entry from a stale one. Both stacks already exported the decoder beside the encoder; only the listing never called it. Fixed in v11 and v12, since the inconsistency is in both. Keying the mirror on the scheme and path stranded every directory written before it: the registry now resolves to a different name, and `list`, `view` and `delete` all scope their glob to the configured registry's current key, so nothing reads the leftover and nothing could remove it. `pnpm cache prune` removes the directories this version can no longer read, across all three metadata roots. New command, so v12 only. `is_unreadable_registry_key` decides what goes. A name carrying no scheme separator predates the current shape, with one exception it must not confuse for staleness: `get_registry_name` collapses a key over 255 bytes to a bare sha256, which carries no separator either. Those are spared, so one unreachable directory can survive rather than a live mirror being deleted. `--dry-run` lists what would go without removing it. The cache directory is shared machine-wide and the scheme-in-key change shipped in v11.27.0 as well as v12.4.0, so a pnpm at 11.26 or earlier still reads the host-only names this removes; a user on both versions can check before paying that CLI a refetch. The ephemeral-port directories the issue also mentions are in the current key shape, so reclaiming them needs a retention policy rather than a mechanism, and are left out. The descriptor-scoped roots under `v11/metadata-private` accumulate equally unreadable directories and are also skipped, as `delete`, `list` and `view` skip them. Also stops `cacheList` and `cacheDelete` from asserting an exact cache listing while the update check resolves `pnpm@latest` through the same cache dir. That check is off under CI, so the stray `pnpm.jsonl` entry only failed these tests locally. Closes pnpm/pnpm#15046. --------- Co-authored-by: Zoltan Kochan <z@kochan.io>

Added pnpm cache prune, which deletes registry metadata cache directories that this version of pnpm can no longer read. Upgrading to pnpm 12.4.0 left one behind for every registry, and no command could remove them #15046.
pnpm cache prune --dry-run lists what it would delete without removing anything.
