[question] indexnow增加实现增量推送功能

[try to solve] Added incremental submit in ops/seo/submit-indexnow.mjs:

1. State file .run/indexnow-state.json (gitignore): records URLs successfully submitted.
2. --incremental: candidate URLs minus those already in state, then POST; write state back on success.
3. --baseline: write currently collected URLs into state without POST (avoids a full re-push after cold start).
4. --since-git <ref>: map git diff ref...HEAD tool/page changes → multilingual URLs; when used alone, does not pull the full sitemap.
5. --reset-state / --state-file / --no-save-state.
6. npm scripts: indexnow:incremental, indexnow:baseline, indexnow:since-git; docs synced in ops/README.md, docs/SEO_PUBLISH_CHECKLIST.md.

Checks: --baseline --remote-sitemap wrote 420; then --incremental pending=0; --since-git HEAD~3 --dry-run expands changed-tool URLs.
