## Description

RK Smart Internal Linker analyzes your content in real time and suggests the most
relevant internal posts to link to — right inside the Gutenberg sidebar. No external
APIs, no monthly fees, no data leaving your server.

**How it works:**

 1. On activation, the plugin creates a keyword index table and begins indexing your
    published posts via WP-Cron (20 posts every 5 minutes).
 2. When you open a post in the editor, the plugin extracts the top keywords and scores
    every other post by keyword overlap (TF-IDF).
 3. The top 5 results appear in a sidebar panel with **Copy Link** and **Insert Link**
    buttons.

**Features:**

 * 100% local — no API keys, no external calls
 * TF-IDF keyword scoring for smart relevance
 * Background indexing via WP-Cron (server-friendly batches)
 * Instant re-index on post save
 * Clean Gutenberg sidebar with score badges
 * One-click copy or insert links
