Agent presets: every card that composes carries a gear that opens the
preset's detail page (breadcrumb, name, marks, description) and declares a
`settings.agentPreset.detail` slot for the sections other plugins contribute.
Plugin manager: the session-plugins group leaves the tab for the detail
page's Capabilities section, with a red Delete on rows the person added and
an Add menu over the installed modules the preset lacks; the manage tab now
precedes the configuration tab.
Plugin configuration: the scope switch is gone. The tab edits the values
shared by all presets, and the same cards form the detail page's Settings
section, registered under a second keyed slot
(`settings.agentPreset.plugin.item`) and editing the preset's own scope while
the page is open. The roster dependency the switch needed leaves with it.
Web e2e goldens, both READMEs of each package, the Agent Note, the slot
catalog, and the inspect catalog follow.
