feat(plugin-inventory): flat plugin list with a default-open toggle guard

The plugin-list tab rendered one flat list of every Loader entry — no separate
"system plugins" section — with each card showing its real enabled state and an
enable/disable button (a required plugin shows only a read-only note). The
enable/disable guard flipped from default-protect to default-open: only the
small REQUIRED_PLUGINS core (entry tree, Remote RPC spine, session/agent spines)
is protected from being disabled, so the shipped plugins are actually
toggleable. Tests, host READMEs, and the enable-disable agent note track the new
grouping and guard.

 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 by current state: disabled plugins sit in the main list with an enable button (so they can be re-enabled), while enabled plugins sit in a collapsible "system plugins" section — a user-added enabled plugin keeps a disable toggle, a required one shows none.
