docs(readme): add comparison table, screenshots, and restructure layout

Add competitor comparison table (vs Vibe Kanban, Aperant, Cursor, Claude Code CLI)
sorted by unique advantage strength. Add screenshot thumbnails around logo.
Restructure sections: Installation first, Comparison after features.
Rename TODO to Roadmap. Add new feature descriptions (review workflow,
workflow history, built-in editor, task dependencies, attachments, autonomy).
