The fixture plugin's rows join `sidebar.workspaces.session.menu.item` after
the shipped rows, the first one opening the plugin group with
`separatorBefore`, and dismiss the menu through `useMenuOpenState`.
The Plugins page declares three slots as children of its main entry:
`plugins.item` lists an official plugin's page in the Official group,
`plugins.bundle.config` renders a bundle's own form on its page, and
`plugins.row.config` gives a row a configure control opening the row's
page. Every entry renders in the `summary` and `page` views the page
passes as owner props; the page draws the title, icon, and crumb and
projects the ledgers beside its store, naming no configurable plugin.
`ui-settings-plugins` registers its four host-plane pages into
`plugins.item` while the Host serves their namespaces and withdraws them
when it stops; the forms keep edits until a save and drop them on leaving
the page, so the discard control and the unsaved marker are gone. The
Settings section becomes the Built-in plugins shell around the inventory
tab, and `settings.plugin.item` is retired.
The Official group opens with the optional bundles the installation
ships, tagged Beta where the feature is one and without an official tag,
followed by the configuration pages. Auto review leaves the optional
bundles and the CLI's dependencies; the install guide names it as its
example spec. The version tag is a capsule like the other tags.
The `plugin-config` web lane drives the pages through the real wire and
opens a community fixture's row page after switching its bundle on; the
settings lanes re-record the renamed navigation entry.
`dsh.title` was a manifest field this branch introduced: the manager read
it for `listBundles` and `inspect`, and the Web page showed it over the
package name. A bundle is named by its package name now, so `DshManifest`
keeps only its shipped fields, the page derives every heading from the
name, and the install dialog's subject line reads the name the Host
answered. The two e2e fixtures drop their titles and the manager lane's
goldens follow.
