-1b. `system/plugin_install` → muted note `⚙ plugin install · loading…`
-   (on `started`) or `⚙ plugin install · ✓ done` (on `completed`).
-   Emitted in pairs: started fires before the plugin loads, completed
-   fires when it's ready. The `uuid` links the pair.
-1c. `system/commands_changed` → collapsible `.note` details row showing
-   the new slash-command count (`⚙ commands changed · N available`).
-   Expanding reveals each `/name` and its aliases. Fires after
-   `plugin_install` when a plugin registers new commands.
-1d. `system/compact_boundary` → muted note showing compaction summary:
-   `⚙ compact · <trigger> · <pre>→<post> tokens · <dur>`. Fields are
-   guarded individually — a missing field is silently omitted. Trigger
-   is `"manual"` (operator `/compact`) or `"auto"`.
