Initial commit: AutoBlogger v0.1.0

WordPress plugin that auto-researches topics from Reddit, generates
SEO-optimized articles via OpenRouter LLMs, runs them through a chief
editor agent, and publishes on a daily schedule.

Includes:
- Full generation pipeline (collect → analyze → score → generate → review → publish)
- Cost tracking and budget enforcement
- Admin UI: settings, review queue, metrics, activity log
- CI/CD pipeline (GitHub Actions → WordPress REST deploy)
- Unit test suite (PHPUnit + Brain Monkey)
- Structured logging with configurable verbosity
