chore: baseline V8.10.0-dev.1 with v8_workflows type-mapping fix and trade-pro spec

- SiteForge Enterprise V8.10.0-dev.1 upstream source (210 tests)
- Fix: v8_workflows._mapped_input now reads both 类型/分类 columns so WXR
  imports keep post/product types instead of collapsing to page
- Docs: trade-pro theme port spec (R3) and implementation plan
