v0.13: add Quarto/xelatex PDF engine and fix ReportLab wide-table rendering

build_report.py: - add --engine quarto option: Quarto 1.9 + xelatex pipeline with CJK font setup (Source Han Serif/Sans CN via fontspec), automatic {.landscape} wrapping for wide tables (>=8 cols), TOC/references placeholder replacement, sources.jsonl backfill - prepare_qmd(): converts Markdown to .qmd with proper YAML front matter, writes _preamble.tex for longtable/pdflscape/lscape packages - _detect_wide_tables(), _build_references_block(): helper functions - ReportLab path unchanged (remains default) report-template.py: - render_table(): force equal-width column distribution for tables with >=4 cols or any cell >30 chars, preventing negative availWidth crash on mixed CJK/English content - render_table_blocks(): split long tables (>25 rows) into chunks to avoid NoneType comparison crash in ReportLab splitByRow logic .gitignore: - add rules for LaTeX temp files (*.aux, xetest.*, *.qmd, _preamble.tex) - add projects/ to gitignore (research data, not source code) README.md: - update status to v0.13 - rewrite PDF section as dual-engine guide with install steps, comparison table, and landscape table chunking guidance - add Quarto troubleshooting (font italic mapping, tlmgr path, param_size) - add v0.13 to changelog
v0.12.1: select model profile at init and carry via manifest

+  **变更**：
+  - 新增 `scripts/search.py`：统一搜索入口，支持 `--route scholar|patents|news|general` 与 `--profile biomed_literature|patent_heavy|china_market|investment`。
+  - `scripts/lib/search_client.py` 调整为 Serper / Exa / Tavily 路由：文献走 Serper Scholar，专利走 Serper + Google Patents，新闻走 Serper News，通用搜索走 Exa → Tavily。

+
+  **目标**：并行解决三项瓶颈：

+  2) 模型选择被硬编码锁定；
+  3) Phase 4 串行链路耗时过长。
+
+  **Track A — 搜索路径可控化（Sprint 1）**：
+  - 新增 `scripts/ground.py`，统一封装 ZenMux native grounding（`web_search_options`）并输出引用 URL。
+  - `scripts/lib/zenmux_client.py` 增加 `web_search` 参数透传与 `chat_complete_with_meta()`（返回 content/usage/citations/raw）。
+  - `scripts/lib/search_client.py` 对 `scholar/patents/news` 默认启用 strict 模式，Serper 异常时显式失败，禁止静默降级。
+  - `scripts/search.py` 增加 `--strict-specialized`、`--trace`、`china_market` 查询重写。
+  - `.opencode/opencode.json` 关闭 Tavily/Brave/Exa MCP 的默认启用，收敛到项目内搜索网关。
+
+  **Track B — 模型配置化（Sprint 2-3）**：
+  - 新增统一配置 `configs/models.yaml`（`simple/medium/premium/cn_heavy/codex_native`）。
+  - 新增 `scripts/lib/model_config.py`，支持 profile 解析、override（`ROLE=MODEL`）与 profile 列表。
+  - `scripts/dr.py` 新增 `models`、`apply-models`，并让 `finalize` 支持 `--model-profile` 与 `--model-override`。
+  - 新增 `scripts/apply_model_profile.py`，可将 profile 批量回填到 `.opencode/agents/*.md` 与 `codex_adapter_templates/codex/agents/*.toml`。
+  - 新增 OpenCode 命令：`/dr-models`、`/dr-apply-models`。
+
+  **Track C — Phase 4 替代式重构（Sprint 4）**：
+  - 新增 `scripts/phase4_pipeline.py` 作为统一编排入口：
+    `translate -> glossary(optional) -> apply_glossary -> polish -> build_report`。
+  - glossary 核查支持 `off/low-confidence/full`，默认 `low-confidence`；低置信度条目过多时自动回退 `full`，避免超长命令参数。
+  - translate/polish workers 支持自动估算（`0 => auto`），降低人工调参成本。
+  - `scripts/dr.py finalize` 与 `.opencode/commands/dr-finalize.md` 切换到新 pipeline。
+
+  **Sprint 5 回归验证**：
+  - 新增 `scripts/sprint5_regression.py`，覆盖模型预设解析、搜索网关 dry-run、Phase 4 finalize dry-run 三项关键回归检查。
+  - 文档同步：`README.md`、`docs/model-playbook.md`、`docs/search-playbook.md`、`docs/codex-usage.md`。
+
+  **Sprint 6 收尾验收**：
+  - AGENTS.md 的 Phase 4 描述更新为 v0.12 真实链路（`dr-editor-in-chief + scripts/phase4_pipeline.py`）。
+  - README 增补一键回归命令：`uv run python scripts/sprint5_regression.py <slug>`。

+    1) `dr.py models --list` 可列出预设；

 - 字体：思源宋 + 思源黑 + 霞鹜文楷（全 SIL OFL，可商用嵌入）

- 图表：matplotlib 预渲染 300 DPI PNG 嵌入
+- 速度：30,000 字 3-5 秒出稿
+- 局限：超宽表格（≥4 列且含长文本）需借助列宽 patch 或改为 bullet list 格式
+
+#### 引擎 B：Quarto / xelatex（`--engine quarto`，推荐用于宽表报告）
+
+```bash
+uv run python scripts/build_report.py <slug> --engine quarto
+```
+
+- 排版引擎：xelatex（TeX Live / TinyTeX），LaTeX 级排版质量
+- 字体：同样使用思源宋 + 思源黑，通过 fontspec 加载
+- 宽表支持：超宽表通过 `longtable` + `tbl-colwidths` 精确指定列宽比例，不溢出
+- 横向页面：通过 `{.landscape}` div 包裹超宽表，自动插入 `pdflscape` 代码（注意：101 行以上的 landscape longtable 可能触发 TeX `param_size` 上限，建议拆成 ≤20 行的子表块）
+- 图表：暂不嵌入 matplotlib 图表（使用文字描述代替）
+
+**安装 Quarto 引擎**（一次性，系统级）：
+
+```bash
+# 1. 安装 Quarto CLI
+#    下载页：https://github.com/quarto-dev/quarto-cli/releases/latest
+#    Linux 选 .deb 安装包，macOS 选 .pkg

+
+**`TeX capacity exceeded [parameter stack size]`**（landscape 大表）：
+
+pdflscape 的 `\LS@makefcolumn` 在 101 行以上的 longtable 里递归过深，耗尽 TeX 的 `param_size`。解决方法：把超大表拆成每块 ≤20 行的子表，每块都包在 `{.landscape}` div 里：

 Codex 的平台限制是：subagents 不会仅因为 `.codex/agents/*.toml` 存在就自动启动，必须由当前主线程明确要求。`dr-run` 已把这个要求写进 PM prompt：Phase 1 会调度 `dr-plan` / `dr-searcher`，Phase 2 会调度 `dr-analyst` / `dr-verifier`，Phase 3 会调度 `dr-chief-editor`。
