rdmbair15m5-changelog-20260822-1631-rddb-modern-liquid-glass-ui-and-stacked-labels

• Scope: rdmbair15m5 (native UI & app) & rdmsm4x:~/dev/apps/rdDB.
• Summary: Redesigned and modernized rdDB.app's UI inspired by FileLabeler — featuring availability-gated Liquid Glass card surfaces (rddbGlassCard, rddbGlassInset), dedicated vertically stacked Airtable-style taxonomy chips (StackedTaxonomyColumn), horizontal quick-filter pills (All, BNY 1WTC, Virtu, Arista, Apple, PDF, Configs), elevated summary metrics banner, and a rich stacked label section in the inspector.

UI Modernizations Delivered

1. Liquid Glass Surfaces & Insets:
   • Implemented rddbGlassCard(cornerRadius: 12) and rddbGlassInset(cornerRadius: 8) with macOS 26+ glassEffect and thin material fallbacks.
2. Dedicated Stacked Labels Column:
   • Replaced sparse multi-column tables with a compact, structured "Stacked Labels & Taxonomy" column displaying customer, solution, archetype, and vendor chips in clean vertical pill stacks.
3. Quick-Filter Capsule Bar:
   • Added instant one-click filter pills at the top of the library to slice by customer (BNY, Virtu), vendor (Arista, Apple), or file type (PDF, Config).
4. Elevated Metrics Banner:
   • Glass summary header displaying real-time counts for Indexed files, Categorized records, Duplicate groups, and Reclaimable disk space.
5. Modern Inspector Panel:
   • Re-architected with glass cards for header info, quick actions ("Show in Finder", "Open File", "Apply macOS Finder Tags"), stacked 5-level taxonomy breakdown, storage metadata, and extracted text preview.
