Subject: [PATCH 1/2] Address review: sanitize post HTML and extract serve.mjs

- Run marked output through sanitize-html so AI-generated/untrusted post
  Markdown can't inject <script>, event handlers, or javascript: URLs
  (verified: script/onerror/javascript: stripped, normal content kept).
- Replace the inline one-liner serve script with scripts/serve.mjs
  (readable, adds path-traversal guard and proper MIME types); drop the
  dead s.writeCode?0:0 expression.

- scripts/providers/: pluggable backends selected by env —
  anthropic (Claude, claude-opus-4-8, adaptive thinking), openai, and a
  zero-dependency dryrun stub so the pipeline runs with no API key.
  SDKs are optionalDependencies, imported dynamically.
- memory/ with an example note as the input source.
- .github/workflows/generate.yml: scheduled/manual generate -> PR to
  develop for human review (never publishes directly).
- npm run generate; README + AGENTS document the memory->AI->PR flow.
- Verified end to end: dryrun generate -> build renders the post; missing
  ANTHROPIC_API_KEY errors clearly instead of failing silently.

+`scripts/generate.mjs` reads recent notes from `memory/`, asks the selected AI
+provider to distill them into one article, and writes it to `posts/`. Provider
+selection (`scripts/providers/index.mjs`): `OPENBLOG_PROVIDER` override, else

+- 读到一句话:「工具的价值不在于它能做什么,而在于它让你不必做什么。」一直在想,博客最该被自动化掉的不是「写」,而是「坚持写」这件事本身。
+- 试着把一天里冒出来的念头随手记到这个 memory/ 目录,哪怕只是一句话。它们是原料,不是成品。
+- 一个观察:碎片想法之所以容易丢,是因为它们没有「被处理」的下一步。如果记下来之后会自动被沉淀成一篇文章,记录的动力就完全不一样了。
+- 待深入:记忆 → 文章 的转化,关键不是润色,而是「从一堆零散里找出那条主线」。
