fix: use Vite virtual module for configuration instead of global state

The initial config-store approach failed because Astro's injected routes run in isolated contexts during prerendering and don't have access to global state set during astro:config:setup. Solution: Created a Vite plugin that provides the configuration through a virtual module (virtual:@astrojs/discovery/config) which routes can import at build time. Changes: - Added Vite plugin in astro:config:setup hook - Updated all route handlers to import from virtual module - Changed version from date-based (2025.11.03) to semantic (1.0.0) per npm requirements - Added @ts-ignore comments for virtual module imports Testing: Verified in test project that all configuration now properly passes through to generated files (robots.txt, llms.txt, humans.txt).

+# @astrojs/discovery - Project Summary
+
+## Overview
+
+A comprehensive Astro integration that automatically generates discovery files for websites, making them easily discoverable by search engines, AI assistants, and humans.
+
+## What Was Built
+
+### Core Features
+
+1. **robots.txt Generator**
+   - Default allow-all policy for search engines
+   - LLM-specific bot support (Anthropic-AI, GPTBot, Claude-Web, etc.)
+   - Custom agent configurations
+   - Crawl delay settings
+   - Sitemap reference
+
+2. **llms.txt Generator**
+   - Site description and key features
+   - Important pages for AI assistants
+   - Specific instructions for AI behavior
+   - API endpoint documentation
+   - Technology stack information
+   - Brand voice guidelines
+   - Custom sections support
+
+3. **humans.txt Generator**
+   - Team member information
+   - Thanks/credits section
+   - Site technical details
+   - Project story/history
+   - Fun facts
+   - Development philosophy
+   - Custom sections
+
+4. **Sitemap Integration**
+   - Automatic integration with @astrojs/sitemap
+   - Pass-through configuration
+   - Centralized sitemap-index.xml
+
+### Technical Implementation
+
+**File Structure:**
+```
