feat: Add Web API with automated data generation

- Implements REST API at /api/ for web-based tool discovery
- Provides client-side UI at /api/client/ for browsing tools
- Auto-generates JSON data from YAML files via multiple methods:
  • Jekyll plugin for GitHub Pages builds
  • Git pre-commit hook for local development
  • GitHub Actions workflow for CI/CD
  • NPM scripts for manual control
- Adds comprehensive documentation (AUTOMATION.md)
- Includes 186 pre-built tool JSON files for instant access
- Features semantic search with same scoring as MCP server

The Web API complements the MCP server:
- MCP: Local stdin/stdout for AI assistants
- Web API: GitHub Pages compatible for browsers

+# API Data Automation
+
+This document explains how the API data is automatically generated and kept in sync with the project YAML files.
+
+## Overview
+
+The Web API (`/api/client.html`) uses pre-built JSON data for performance and GitHub Pages compatibility. This data is automatically generated from the YAML files in `_data/projects/`.
+
+## Automation Methods
+
+### 1. Jekyll Plugin (Automatic on GitHub Pages)
+- **File**: `_plugins/api_generator.rb`
+- **When it runs**: During every Jekyll build
+- **How it works**:
+  - Reads all YAML files from `_data/projects/`
+  - Generates combined JSON (`api/data/projects.json`)
+  - Creates JavaScript module (`api/data/drupal-tools-data.js`)
+  - Creates individual JSON files for each project
+
+### 2. Git Pre-commit Hook (Local Development)
+- **File**: `.git/hooks/pre-commit`
+- **When it runs**: Before every commit
+- **What it does**:
+  - Checks if any YAML files were staged
+  - Runs `npm run build-api` if changes detected
+  - Automatically stages the generated API data
+
+### 3. GitHub Actions (CI/CD)
+- **File**: `.github/workflows/build-api.yml`
+- **When it runs**: On pushes to main/master, pull requests, or manual trigger
+- **Features**:
+  - Builds API data in isolated environment
+  - Commits generated data back to repository
+  - Ensures API is always up-to-date
+
+### 4. NPM Scripts (Manual Control)
+```bash
+# Build API data once
+npm run build-api
+
+# Watch for changes and rebuild automatically
+npm run watch-api
+
+# Build and stage before committing
+npm run precommit
+```
+
+## Data Flow
+
+```

+## File Structure After Build
+
+```
+api/
+├── data/
+│   ├── projects.json           # All projects + metadata
+│   ├── drupal-tools-data.js    # JavaScript module
+│   ├── blt.json               # Individual project data
+│   ├── acquia-desktop.json    # Individual project data
+│   └── ...                     # One JSON per project
+├── client.html                 # Web UI
+├── index.html                  # API documentation
+└── drupal-tools.js            # Client library
+```
+
+## Troubleshooting
+
+### API data is out of sync
+Run: `npm run build-api`
+
+### Pre-commit hook not working
+```bash
+chmod +x .git/hooks/pre-commit
+```
+
+### GitHub Actions failing
+Check: `.github/workflows/build-api.yml`
+
+### Local development with auto-rebuild
+```bash
+npm run watch-api
+```
+
+## Performance
+
+- Initial load: ~50KB of JSON data
+- Search: Instant (client-side)
+- No external dependencies on GitHub Pages
+- Cached by browsers for 1 hour
