chore: migrate GRACE-Poly anchors to hierarchical dotted naming

Systematic rename of all semantic anchors (#region, [DEF], @RELATION)
across 1400+ files — backend Python, frontend Svelte/TS, specs, docs:
- Flat anchors become Namespace.Module.Entity
- @RELATION references updated to match new anchor paths
- Zero business logic changes
