feat(plugin-inventory): group by enabled state and allow re-enabling disabled plugins

The plugin-list tab now splits by current state: disabled plugins sit in the
main list with an enable button (so a bundle-default-disabled plugin can be
re-enabled), while enabled plugins sit in the collapsible system section —
a user-added enabled plugin keeps a disable toggle, a required one shows
none. setEnabled refuses to disable a required plugin but allows re-enabling
a disabled one, verifying the fiber activates and reverting a
dependency-missing enable.

 The phase is `pending`, `loading`, `active`, `failed`, or `unloading`; it is `null` when the entry has no live root Fiber. The snapshot is intentionally point-in-time: Loader remains the sole lifecycle authority, while this package owns no cache, history, provenance model, or event stream. `setEnabled` toggles one entry live through `ctx.loader.update` and persists an explicit `disabled` override into the profile's user patch layer so the choice survives a restart (a bundle-default disable needs the `disabled: false` override to stick).
 
-Every entry carries a `protected` flag. The guard is default-protect: every shipped plugin is required by the application (disabling one that another plugin injects breaks the dependent; enabling one whose service is unavailable fails the boot), so `setEnabled` refuses them and the UI hides the toggle. Only plugins a deployment adds through an opt-in bundle (`USER_TOGGLEABLE_PLUGINS` in `src/required.ts`) are toggleable. The Web plugin-list tab groups the inventory accordingly: toggleable plugins carry an enable/disable button, while the required system plugins sit in a separate collapsible "system plugins" section with no controls. Its public payload types live under `./types`, and Typert generates the Host and Client Remote artifacts exposed by `./typert` and `./remote`.

 The service is Remote-only and deliberately declares no same-process Cordis `Context` merge. Client packages consume it through the explicit [`api-remotes`](../../api/remotes/README.md) assembly rather than importing the Host implementation.
