html_export_graph_page

Html export should provide an interactive graph page with search, filters, and links back into idea and cluster pages.
The graph should support scoped views for workspace, file, cluster, and idea contexts.
The workspace graph page must include every idea in the export scope — blocks, oneliners, and ideasets — and must not apply the interactive Ideas Summary GRAPH_MAX_NODES budget.
Ideasets are visible by default with a Hide ideasets / Show ideasets toggle, matching the external-file visibility control.
Status and tag filters are multi-select and distinguish graph_status_tag_filters.
Per-idea, per-file, and per-cluster neighbourhood graphs may still use a capped budget for focused pages.
