Update 02/03 1b+2b (en,zh,es,ja), inventory #62, README

Gates until green:

npm run merge:tools && npm run coverage:gate -- --slug=pdf-page-to-image-sizes --phase=all && npm run build:site && npm run lint:seo && CROSS_TOOL_UPDATE=1 TOOL_SLUG=pdf-page-to-image-sizes npm run lint:tool-isolation

No plan/commit. 中文 brief. Chinese comments on functions.

Also double-check inventory lines 52-62 are all 已上线; if any still 未开始, fix them.

• fflate@0.8.2 packs page-{n}-{WxH}.jpg → page-{n}-sizes.zip
• Page number input (default 1); 25 MB soft warn; readable encrypted/corrupt errors
