docs: add checkpoint files for state tracking

Add STATE.scm, ECOSYSTEM.scm, and META.scm for project state management:
- STATE.scm: Current project state, tasks, blockers, milestones
- ECOSYSTEM.scm: Relationships to other projects in ecosystem
- META.scm: Architectural decisions and development practices

These files enable AI assistants and tools to understand project
context and make informed decisions about changes.

Part of RSR (Rhodium Standard Repository) compliance.
