feat(catalog): activate construction_bim_three_usage (IMP-04 Track A 3/16)

Reason : V4 UAI=1 (01-1) + RS=1 — UAI tier strongest after F12. Track A
frame 3 per Codex round 39 V4-priority acceptance.

3-layer architecture context (matrix §0) :
- V4 = matching authority — V4 ranked this frame as use_as_is for 01-1
  ("용어 정의") and restructure=1 for other sections.
- figma_to_html (1171281182) = rich source/evidence — 401-line index.html
  + 4 PNG assets, full A+T+I+F+S resource available.
- Phase Z = runtime orchestration — this commit adds catalog + partial +
  smoke fixture for the runtime projection.

Builder reuse (Codex round 39 secondary criterion) :
- Reuses existing `quadrant_flat_slots` (F16) with pad_to=3 +
  label_key_pattern="category_{n}_label" + body_key_pattern="category_{n}_body".
- Same parser `quadrant_item` reused — no new builder or parser added.
- F16 / F11 share flat-keyed label+body grammar; only N differs (4 vs 3).

3 file changes :

1. templates/phase_z2/families/construction_bim_three_usage.html
   - Adapted from figma_to_html_agent/blocks/1171281182/index.html.
   - 3 horizontal stacked rows (brown label box + white card with green
     border, per Figma L82-103). Compact Phase Z zone fit.
   - PROMOTED CSS : brown label box (rgba(50,31,9,0.8) + 둥글기 + drop-
     shadow), white card with green border (#A5BBB4), title gradient
     (#000 → #883700 F13/F14/F12 family), bullet markers in brown family.
   - NOT PROMOTED (P1 case-by-case + preservation guardrail per Codex
     round 37 / matrix §4.1 Fix 7) : title-icon (50×50 small), card_decor
     × 3 (decorative side images), bottom BIM 모델/공사 Process 다이어그램.
     Figma source evidence preserved in figma_to_html_agent/; not promoted
     to Phase Z compact projection.
   - ADAPTED : Figma 50/45/38/30 px → token-fixed, 1248×1066 absolute +
     zoom 0.67542 → Phase Z flex column 3-row stack, 335×124 label box
     → 110×~50 compact (zone fit).

2. templates/phase_z2/catalog/frame_contracts.yaml
   - F11 contract appended after F12.
   - frame_id=1171281182, family=cards, source_shape=top_bullets, strict
     cardinality 3, role_order=[category_1, category_2, category_3].
   - visual_hints.min_height_px = 320 (title 30 + 3×70 row + gaps 12 +
     padding 30 = 282 + 38 safety buffer).
   - accepted_content_types = [text_block] only.
   - 3 sub_zones (category_1/2/3 main_text).
   - payload.builder = quadrant_flat_slots (reuse) with category_{n}_*
     key patterns.

3. scripts/smoke_frame_render.py
   - Bundled fixture for F11 self-check.

Verification :
- python -m py_compile scripts/smoke_frame_render.py : PASS
- python scripts/smoke_frame_render.py --self-check : PASS 6/6 (F11
  added at 3014 chars, compact CSS-only)
- python scripts/smoke_frame_render.py construction_bim_three_usage
  --render-to data/runs/imp04_f11_visual : PASS, R3 artifact written,
  0 raster refs (CSS-only), copy_assets ran (4 PNGs in assets/ dir
  for future fidelity-review if needed)
- python run_mdx03_pipeline.py --phase-z2 --run-id imp04_f11_regression
  : PASS (MDX 03 V4 rank-1 still F13/F29, F11 not triggered for MDX 03 —
  F11 only routes 01-1 per V4 evidence)

scope-lock honored (3-layer + 4-class) :
- V4 logic / V4 evidence yaml : unchanged
- Existing PAYLOAD_BUILDERS 4 builders (incl. F12's cycle_intersect_3) :
  unchanged. F11 reuses quadrant_flat_slots (secondary criterion).
- Existing ITEM_PARSERS : unchanged. F11 reuses quadrant_item.
- Existing partials (F13/F29/F16/F14/F12) : unchanged.
- Composition planner / production render path / Phase R' / AI/Kei :
  unchanged.

4-class status :
- class 1 adapter/runtime readiness : ✅ contract + builder + partial +
  smoke fixture + R3 artifact aligned.
- class 2 content-fit : watch — 3 rows × ~70 px height. If MDX body has
  4+ bullets per category, may overflow. realistic use case (01-1) shows
  1-2 bullets per category per analysis.md, so within budget.
- class 3 / 4 : N/A.
