fix(growth): MEDIUM-12 ProfileUpdater 补齐 5 维度画像更新

根因: ProfileUpdater 只处理 industry 和 communication_style 2/5 维度，
跳过 recent_topic、pain_point、preferred_tool。

修复:
- ProfileFieldUpdate 添加 kind 字段 (SetField | AppendArray)
- collect_updates() 现在处理全部 5 个维度:
  - industry, communication_style → SetField (直接覆盖)
  - recent_topic, pain_point, preferred_tool → AppendArray (追加去重)
- growth.rs 根据 ProfileUpdateKind 分派到不同的 UserProfileStore 方法:
  - SetField → update_field()
  - AppendArray → add_recent_topic() / add_pain_point() / add_preferred_tool()
- ProfileUpdateKind re-exported from lib.rs

测试: test_collect_updates_all_five_dimensions 验证 5 个维度 + 2 种更新类型
