IRIS PROMPT STUDIO V2.6.36 — Spatial Editor Generalization

- 2D floor plan object picker grouped into 8 compact categories.
- Added 52 general-purpose object types for domestic, retail, professional, city, nature, underwater, historical and transit locations.
- Added 14 new scene templates alongside the original 7 and blank template.
- Location templates can connect to the corresponding existing place definitions when supported.
- The output inspector now validates active 2D spatial distances in meters and 2D headings instead of checking the legacy centimeters/azimuth strings.
- Existing presets, JSON schema and saved scene object IDs remain compatible.
- World-space visibility remains 2D horizontal approximation, not true 3D.
- Corrected tattoo diagnostic marker to match actual tattoo output.
- Added explicit "Use current background" for any existing location and initial scene label fallback for untemplated locations.
