"""Seeder for the built-in agentfx analyst agent and its report skills.

agentfx 任务深链（新系统 iframe 嵌入的智能体问答）固定使用内置智能体
``agentfx-analyst``：根据任务详情与用户输入搜集信息，把每次检索 JSON 落盘后
用 ``task-report-*`` 技能函数转换成 14 类 ``task-reports.json``，再写 md 研判
报告，总结后经前端「入库」协助卡或 ``task-report-import`` 写入任务详情。

种子内容与 ``forced-research-responder`` 同一套模式：
- ``_agentfx_seed_assets/agentfx-analyst/{config.yaml, SOUL.md}`` → 复制到
  ``{DEER_FLOW_HOME}/agents/agentfx-analyst/``（目录存在则不动，尊重现场修改），
  由启动流程的 ``_sync_legacy_agents`` upsert 进 ``agents`` 表（user_id IS NULL）。
- ``_agentfx_seed_assets/skills/task-report-{build,enemy,our,env,judge,import}/`` →
  复制到 ``skills/public/``（目录存在则不动）；共用引擎
  ``task-report-lib/``（无 SKILL.md，不进技能列表）一并补建。
  ``skills/`` 被 .gitignore 排除，public 类技能在 extensions_config 缺省即启用。

必须在 ``_sync_legacy_agents`` **之前**调用。
