/**
 * Generate oclif.manifest.json for the sf-cli-plugin-data360 community plugin.
 *
 * Why this exists:
 *   `npx oclif manifest` imports every command class, which triggers the
 *   @oclif/core class hierarchy. When the plugin's pinned @oclif/core is
 *   older than what the current Node.js version expects, the import fails
 *   with "Cannot read properties of undefined (reading 'prototype')".
 *
 *   This script avoids importing commands entirely. It walks the compiled
 *   lib/commands/ directory and extracts static metadata from source text
 *   via regex, producing a valid manifest that tells oclif to skip
 *   auto-discovery and auto-transpilation.
 *
 * Usage:
 *   node generate-manifest.mjs            # uses cwd
 *   node generate-manifest.mjs /path/to   # uses explicit plugin root
