/**
 * Inspection and cleanup helpers for the AFT plugin's LSP cache.
 *
 * Two roots are populated by the plugin auto-installer at startup:
 *
 *   <aft-cache-root>/lsp-packages/<urlencoded-pkg>/   ← npm installs
 *   <aft-cache-root>/lsp-binaries/<id>/               ← GitHub-release downloads
 *
 * The CLI reports their disk usage in `aft doctor` and can purge them via
 * `aft doctor --force`. Purging is non-destructive in the sense that the
 * plugin will simply re-install whatever the project needs on next session;
 * it does not delete user-installed binaries (those live on PATH).
