catalog: lifecycle field replaces the retired/ directory move

Moving a template out of templates/ un-offers it but also makes the
controller's orphan detector see it as GONE for anyone already running the
app - flagging their working install Elavult with a Torles button. Withdrawing
an app must never take a working app away from a customer.

Optional lifecycle: available|hidden|abandoned in .felhom.yml instead.
plant-it returns to templates/ as the first abandoned app; retired/ removed.
Resolvability gate skips (and reports) non-available apps.

+# --- Lifecycle ---
+# abandoned: upstream stopped developing the self-hosted edition. NOT offered for new installs;
+# anyone already running it keeps running it, with a permanent notice that no updates or security
+# fixes will arrive. Evidence (2026-07-21): the `backend/` and `deployment/` directories are DELETED
+# from upstream `main` (the project is now an Android app on F-Droid/Obtainium); the last server
+# image `msdeluise/plant-it-server:0.10.0` was pushed 2024-12-10 and is a security-frozen Spring
+# Boot 3.4.0; and it requires MySQL 8.0 + Redis, which this template never had.
+#
+# The compose below is deliberately LEFT AS-IS (it pins `msdeluise/plant-it:0.10.0`, a repository
+# that does not exist — the real one is `-server`). It is not worth fixing: the app is not
+# installable, and rewriting it would imply it is.
