/**
 * `agentsmarket clean` — wipe local state for one or all categories.
 *
 * Categories (combine freely):
 *   --identity     config.json + agent.key + payment.key + mnemonic.txt
 *   --pipelines    $AGENTSMARKET_PIPELINES_DIR (or ~/.config/agentsmarket/pipelines/)
 *   --skills       $AGENTSMARKET_INSTALL_DIR (or detected agent dirs)
 *
 * Default (no flags) = --identity --pipelines --skills (= --all).
 *
 * Without --yes, prompts before each destructive step. With --yes, deletes
 * everything matching the chosen flags. Use --dry-run to print what would
 * be deleted without touching disk.
 *
 * Safe semantics:
 *   - Files that don't exist are skipped silently (not an error).
 *   - Recursive delete refuses to follow symlinks (no escape via symlink).
 *   - Each deletion is logged so users can audit.
