Surfaces the hotfix channel in the WebUI. Primary home is the Updates &
Improvements page (the updater component) — its own "Improvements" tab — with a
secondary chip on the App detail page (fork 3 locality = both).
Updater component (components/updater):
- New "Improvements" sidebar tab + panel; renderImprovements() reads the host-
generated artifacts_available.json (severity badge, scope chip, applied/auto/
not-applicable badges, plain-English why). Apply/Revert buttons dispatch
artifact_apply / artifact_revert through the TASK system (services.tasks.route)
— no mutating API. Apply is disabled when the index is UNSIGNED.
- Overview gains an "Improvements" stat card; task-refresh now also repaints on
artifact_* task completion; URL tab routing + dispose teardown extended.
Task plumbing (core/tasks): artifactApply/artifactRevert action methods (id is
charset-guarded before it enters the command string) + artifact_apply/
artifact_revert routeAction cases. Task list/format gain icons + friendly labels.
Apps component: an amber "⚡ N improvements" chip on an installed app's detail
header (populated async from artifacts_available.json filtered by app, applicable
& not-applied), linking to /updater/improvements. Best-effort, never throws.
