Date: 2026-08-14 20:38 Summary: Update documentation for the default incremental build and deploy flow.

[question] 更新相关的文档

[try to solve] Updated the remaining documentation that still described full upload/build as the default. The docs now say build:site, upload:r2, and deploy are incremental by default, while build:site:full, upload:r2:full, and deploy:full are the explicit full rebuild/reupload paths. The SEO checklist, Worker+R2 design doc, Copilot instructions, README, and ops troubleshooting notes now match the current flow.
