Date: 2026-08-08 19:44 Summary: Shipped inventory #50–51 merge-pdf and split-pdf with coverage gates, ten-locale i18n, and build:site.

[question] 立项并串行实现 merge-pdf / split-pdf（#50–51）— Implement the plan as specified.

[try to solve] Completed both tools serially under tool-coverage-pass:

1. Parallel briefs + coverage:gate --phase=0b for merge-pdf and split-pdf.
2. Implemented merge-pdf (pdf-lib CDN, reorder list, sample auto-merge) through phase 2/4, ten locales, build:site, lint:seo.
3. Implemented split-pdf (every page / ranges, fflate ZIP for multi-file, sample auto-split) through the same gates.
4. Updated README and inventory #50–51 → live; catalog now 46 tools; both coverage:gate --phase=all green.
