feat: integrate Shipyard Neo self-iterating skill loop and dashboard controls

[w31r4]

Modifications / 改动点

• 接入 shipyard_neo 运行时基线：新增 ShipyardNeoBooter，支持 python/shell/filesystem/browser 能力，并在 sandbox 配置中新增 Neo 所需字段（endpoint/token/profile/ttl），默认 booter 调整为 shipyard_neo（仍保留 shipyard 兼容分支）。

• 新增 Neo 自迭代 Skill 闭环工具链（仅 shipyard_neo 挂载）：

  • 执行与取证：astrbot_execute_browser / astrbot_execute_browser_batch / astrbot_run_browser_skill / astrbot_get_execution_history / astrbot_annotate_execution
  • 迭代生命周期：astrbot_create_skill_payload / astrbot_get_skill_payload / astrbot_create_skill_candidate / astrbot_list_skill_candidates / astrbot_evaluate_skill_candidate / astrbot_promote_skill_candidate / astrbot_list_skill_releases / astrbot_rollback_skill_release / astrbot_sync_skill_release

• 新增 NeoSkillSyncManager：

  • stable release -> 本地 data/skills/<local_skill_name>/SKILL.md 回写
  • 维护 data/skills/neo_skill_map.json
  • 回写后激活本地 skill，并最佳努力刷新活跃 sandbox 技能
  • stable promote 回写失败时自动 rollback 新 release，保证 Neo 真源与本地可用状态一致

• Dashboard 新增 Neo 管理 API：

  • GET /api/skills/neo/candidates
  • GET /api/skills/neo/releases
  • GET /api/skills/neo/payload
  • POST /api/skills/neo/evaluate
  • POST /api/skills/neo/promote
  • POST /api/skills/neo/rollback
  • POST /api/skills/neo/sync

• Skills 页面新增 Local / Neo 视图切换及关键动作（evaluate/promote/rollback/sync/payload 查看），并补充中英文 i18n。

• 新增/扩展测试覆盖：Neo sync、Neo tools、Neo dashboard routes。

• This is NOT a breaking change. / 这不是一个破坏性变更。
