@fonlan/dsh-model-parameters v0.1.2

• feat: move settings UI to plugin Settings Card (settings.plugin.item)
  • settings UI now appears in 设置 → 插件 → 插件配置 as an expandable card,
    styled like the built-in plugin cards (collapsed by default)
  • client registers into settings.plugin.item keyed by the model-parameters
    namespace (same pattern as dsh-web-auth); host half unchanged
• docs: README updated for the settings card
