feat(bizdev): 成功解析的材料一律写入 material_chunks

大小阈值只决定全文注入还是目录加检索片段,不再决定是否切块。上传后的异步解析同样跳过 60KB 门槛。

# 成功解析的材料一律切块入库
## 目标
项目 6579 的 `doc_proj6579_bd_intake` 正式正文改为候选 535;每份成功解析的材料都写入 `material_chunks`,小文档仍全文注入。
## 范围
- `materialToItems` 在解析成功后无条件 `IndexChunks`,大小阈值只决定注入方式。
- 上传后的 `EnqueueAsync` 同样不再用 60KB 门槛跳过切块。
## 非目标
- 不改职责矩阵,不晋升 test/main,不改 `production_ready`。
- 不替换已过期的 MinerU 精度 token。
## 步骤
1. [x] 编制人一次性会话确认候选 535,并撤销会话
2. [ ] 切块调用移出大小分支
3. [ ] 用项目 6579 已上传 PDF 复核 `material_chunks` 与检索
4. [ ] 单测与报告
## 验收标准
- [ ] 正式正文不再含「二进制压缩流」
- [ ] `material_chunks` 对该 PDF 有行且 embedding 非空
- [ ] `go test -short ./internal/mineru/ ./internal/materialindex/ ./internal/bizdev/` 通过
