v1.1.0 — minimal ablation tier + render_table rework

Second release of the Missing Layer demo. Everything here is backward-compatible with the v1.0.0 rich API.

Added

• Minimal ablation endpoint (mcpMinimal) — a metadata-stripped twin of get_building_profile: one-sentence description, no schema, no curated alerts[]. Same data, no metadata layer, so the paper's thesis can be tested by contrast.
• Apps on the minimal tier — the minimal endpoint exposes the same tool set as rich (get_building_profile + render_chart / render_table / render_map), every tool stripped to minimal instructions. The only variable between the two endpoints is the metadata itself.
• Dual hosted endpoints, documented with a runnable A/B prompt and deep links to the metadata in source.

Changed

• render_table rework — migrated to TanStack Table v9 stable, fixed pagination:false (renders all rows) and global search, refactored footer aggregation.
• README restructured for a conference-first read: paper link → thesis → "try it live" → why → depth.
