release: v0.1.6 — retail frontage changelog entry, TODO pruning

Writes the 0.1.6 entry, removes the completed section from TODO.md (its goal stays
in ROADMAP.md per the convention), and updates the roadmap status line.

-- [x] **Model 6800 Lee Drug and 6806–6820 from their own reference.** Built 2026-11-09 on branch `facade-retail-0.1.6`: `Tools/retail_frontage_build.py` (analysis in `Art/blender/retail/ref-analysis.md`), imported by `Tools/ue_import_retail_detail.py`, staged as `RetailTrim_*`; the generic façade kit skips these two so the wall carries one façade language. Delivered in this patch: bronze cornice, storefront glazing and mullions, framed portrait panels, two-tier parapets with reveals, burgundy fascia, pilasters, white-framed windows with security bars, fluted corner tower. **Moved out:** lettering decal, moulded parapet profile and tower refinement cannot be solved with geometry at this size and are now items under `0.9.0 — Realistic buildings`; the trim that does read is what this patch ships.
-- [x] Review every façade change with `Tools/render_screenshots.sh --verify` before tagging. Done 2026-11-09: 5/5 shots verify OK, scene audit 0 failures, and the owner approved `demo-retail-frontage` (second pass) in `Screenshots/README.md`.
-- [ ] Tag `v0.1.6` and write `CHANGELOG.md` entry; then remove this section.
