Tell linker and organize agents to:
- Name unnamed concepts: when 3+ nodes share a theme with no hub,
create one with WRITE_NODE that synthesizes the generalization
- Percolate up: gather key insights from children into hub content,
so the hub is self-contained without needing to follow every link
This addresses the gap where agents are good at extraction and linking
but not synthesis — turning episodic observations into semantic concepts.
