dsh-session-settings

Per-session settings infrastructure for DeepSeek Harness.

• Host half owns the per-session configuration truth and exposes the sessionSettings service (register / get / set / reset / subscribe). Declarative items are registered from consumer host halves.
• Browser half registers one native right-sidebar tab (id and kind: session-settings) that renders every registered plugin's options for the session the tab belongs to.
• Overrides are stored per session through the official storage domain (<DSH_HOME>/storages/session_settings/); nothing is written into session logs or the profile patch.

Design: docs/design-v1.md.

Status: 可用（宿主服务 + 浏览器页面 + 存储 + 桥接 + 界面）。依赖与升级对照见 docs/dsh-dependencies.md。
