overview_page

First tab: a workspace overview for the active base — product-facing copy ( not index / debug jargon ).
- At a glance: idea count, reference count, issues, bases, and a friendly readiness status.
- Coverage: collapsible overview_coverage_scores ( lazy, non-blocking ).
- Search: live cross-surface search over ideas, ideasets, attributes, and references for the active base;
results group by surface with sample hits and actions to open the matching tab with the query applied ( overview_search ).
- Export: buttons that open export functionality — Export form / HTML, and PDF ( export_webview, features-export.rq pdf path ).
- Links: project site, support / email, GitHub.
- Recent changes preview ( idea names when available ) with a link to timeline_page.
