v0.13.0

Two things in this release: Update Manager is now searchable directly in HACS, and auto-install failures handle themselves much more gracefully.

Update Manager is now in the HACS default store

Search for "Update Manager" directly in HACS. No custom repository needed anymore.

Auto-install failures now back off and keep trying on their own

A user reported auto-install silently failing and retrying over and over on a repeated HACS download error (#12), with nothing showing it was stuck. Tracing it down turned up a real, widespread HACS bug (hacs/integration#5643, not yet fixed upstream), and a gap worth closing either way: a failed auto-install retried every 5 minutes forever, with barely any visibility, and manually clicking Install yourself to work around it gave even less.

Escalating backoff instead (5 min → 15 min → 1 hour, capped), shown exactly like any other scheduled auto-install everywhere in the UI, including for an "Always auto-update" entity, which previously showed nothing at all while quietly failing and retrying. Keeps trying on its own with no further action needed; it should resolve itself once whatever's actually broken gets fixed.

Also in this release

• Clicking Install (or Install all) yourself in the panel gave less failure feedback than an automatic retry. Now shows the same "Failed updates" notification an auto-install failure gets, just without starting an automatic retry of its own.
• A Home Assistant Core (or OS) update could show up in History as install method "External" instead of "Manual", or not make it into History at all, depending on timing. Fixed a third code path that had the same gap two earlier fixes already closed elsewhere.
