chore: Phase 4 cleanup — dedupe RenderOptions, remove unused param, fix test numbering

1. Deduplicate RenderOptions type
   - Remove duplicate definition from liquid-render.ts
   - Import from render.ts instead (canonical location)

2. Remove unused _globalDecay parameter
   - Remove from renderNode function signature
   - Update all call sites

3. Fix test numbering gaps
   - Suite 4: Renumber 4.4→4.2, 4.5→4.3
   - Suite 7→6: Renumber 7.1→6.1, 7.2→6.2, 7.4→6.3
   - Suite 8→7: Renumber all 8.x→7.x tests
   - Suite 10→8: Renumber 10.1→8.1
   - Result: consecutive suite numbering (1-8)

4. CLI test status: All 95 tests pass (no pre-existing failures found)

Fixes #46
