/**
 * WP-Dapp Tag System Documentation
 *
 * This plugin handles tags from multiple sources and manages them for Hive publishing.
 *
 * Tag Sources:
 * 1. WordPress Categories: Automatically converted to Hive tags
 * 2. WordPress Tags: Automatically converted to Hive tags
 * 3. Default Tags: Global tags set in the plugin settings
 *
 * Tag Processing:
 * - All tags from the different sources are combined
 * - Duplicates are removed (array_unique)
 * - Tags are limited to 5 (Hive's maximum) using array_slice
 * - The first tag becomes the "parent_permlink" in Hive (main category)
 * - If no tags are available, 'blog' is used as a default
 *
 * Hive Tag Requirements:
 * - Tags must be lowercase letters, numbers, or hyphens
 * - No spaces or special characters allowed
 * - The plugin automatically converts tags to meet these requirements
 * - Maximum of 5 tags per post
 * - At least 1 tag is required
