feat: 增加公开业务 Agent 目录 (#108)

## 摘要

新增 7 个公开、可复用的 listing-only Agent 条目：

- 内容营销 Agent
- 标书协作 Agent
- 合同审查 Agent
- 工程图校核 Agent
- 检验报告 Agent
- 研究证据 Agent
- 流程运营 Agent

这些条目用于发现和展示能力蓝图，不声明已安装、已连接外部系统或可替代专业人员签发。工程、检验、法律和研究类条目均保留人工复核边界。

## Summary

Add seven public, reusable, listing-only Agent entries for content
marketing, tender collaboration, contract review, engineering drawing
review, inspection reports, research evidence, and workflow operations.

The entries are discovery blueprints only. They do not claim installed
tools, connected systems, or authority to replace qualified professional
review and sign-off.

## 数据变更 / Data changes

- Market version: `1.3.0`
- Agent count: `1 → 8`
- Every Agent includes bilingual legacy metadata and `CatalogItemV1`
sidecar data
- All new entries remain `listing-only` with unknown license/platform
facts where evidence is absent

## 验证 / Validation

- i18n unit tests: 9/9
- catalog validator tests: 29/29
- collection generator tests: 4/4
- catalog validation: 0 errors
- i18n validation: 0 errors
- secret/private-key scan: 0 findings
