Complete rewrite structured around three pillars:
1. The problem (architectural + methodological)
2. The method (ontology, capture/organize, convention over configuration)
3. The foundation (local files, Git, AI-native architecture)
Key improvement: the document now explains *why* tool and method together
is the differentiating insight — not just a list of features and principles.
Includes the three-stage product trajectory and updated design principles.
Current state section condensed; full roadmap moved to ROADMAP.md.
