feat: initialize project skeleton with Go backend, database, and config

- Go module with standard library + gorilla/sessions + mysql driver - Config: env-based configuration with .env file support - Database: MySQL connection with auto-migration for 6 tables - Seed data: 12 system tags with options, 8 system snippets - Auth: session cookie middleware - Handlers: auth, tags, snippets, builder, claude, dashboard, suggestions, settings - LLM: OpenAI-compatible client with 30s timeout - Docker: Dockerfile + docker-compose.yml - .env.example with all configuration options Co-Authored-By: Claude <noreply@anthropic.com>
