perf: deduplicate zh site_libs and images trees against root copies

[ShixiangWang]

Summary

Resolves the A3.2 (zh 站点资源去重) item of #306: babelquarto copies the shared site_libs/ and images/ trees into the rendered zh/ tree as byte-identical duplicates of the root copies, adding ~94 MB to every deploy (measured on the live artifact from PR #330: zh/site_libs 51.6 MB + zh/images 42.7 MB, diff -rq → 0 differences).

Changes

New post-render pipeline step (both publish workflows)

• .github/scripts/rewrite-zh-site-refs.py — resolution-based rewriter: for every zh HTML reference to site_libs/… or images/…, resolves it against the page directory; if the target lands inside zh/ and the root-tree equivalent exists, rewrites it to the root tree's relative path. Non-HTML files are untouched (verified: the only candidate, a dead leaflet.css inside zh/site_libs, is never linked by any page). References whose root counterpart is missing are left as-is and reported.
• .github/scripts/prune-zh-duplicates.py — deletes zh/site_libs + zh/images, but aborts with a nonzero exit if any zh HTML still resolves a reference inside them. A missed rewrite fails the build loudly instead of shipping broken pages.
• Wired into quarto-publish.yml and quarto-publish-update-cache.yml after the zh figure-refs rewrite, before lazy-loading and freeze-cache save.

Chunk-label drift fix (root cause of the only 5 broken zh figure refs)

• Omics/ManhattanPlot.zh.qmd: fig-2.3Hlight → fig-2.3Highlight (matches English)
• Omics/CellChatCirclePlot.zh.qmd: fig1-overall-circle/fig2-individual-circle/fig3-chord/fig4-heatmap → fig-1-overall-circle/fig-2-individual-circle/fig-3-chord/fig-4-heatmap, converted to the #| option style used repo-wide; dimensions preserved. No @fig- cross-references exist in these files (rename-safe).

Measured impact (on a copy of the live artifact)

Metric	Before	After	Δ
Site total	377 MB	282 MB	−95 MB
zh tree	147 MB	53 MB	−94 MB

Validation

• ✅ Rewrite on live-artifact copy: 5,215 refs across 267 pages, 0 unresolved — all resolve to existing root-tree files after pruning
• ✅ Root site_libs/ and images/ bytes unchanged (hash-verified)
• ✅ Prune guard: aborts (exit 1) when a stale ref is injected; idempotent on a clean run
• ✅ Both workflows parse as valid YAML; scripts pass py_compile
• ⏳ PR CI full render will validate end-to-end (freeze covers zh chunks; post-render scripts run fresh each build)
