multi_base_environment

Analytical features are multibase aware via base-registry.ts:
one ideas_index / `WorkspaceIndex` per base, isolated catalogs ( no cross-base idea-id collision ).
Surfaces list all discovered bases; Ideas Summary and context panes scope to the active / selected base ( active_base_switch ).
Cross-base reference resolution and merged graphs are out of scope for the first multi-base pass.
Headless ( CLI / MCP ) selects one base via create-runtime.ts; the editor hosts index-service.ts.
