+- **App installs now copy subdirectories, so dependency hooks actually
+  ship.** `install_from()` only copied an app's top-level files, so the
+  `scripts/` folder — where a provider's `on_install`/`on_start` dependency
+  hooks live — never reached `/var/lib/furtka/apps/<app>/`, and every hooked
+  dependency failed at reconcile with `hook ... missing in provider`. The
+  whole app folder is copied now (`rmtree` + `copytree`, so a reinstall also
+  drops files that were removed upstream). Found during the first real
+  end-to-end run of the mosquitto + zigbee2mqtt pair on a test VM.
+- **`furtka app install <name>` now runs `on_install` hooks.** Named CLI
+  installs copied the app folders and then ran a bare reconcile, which fires
+  `on_start` but never `on_install` — so a CLI install of a consumer brought
+  its provider up without ever provisioning it (no account created, empty
+  `MQTT_*` values in the consumer's `.env`). Named installs now go through
+  `install_runner.run_install` (writing the plan file first), the same docker
+  phase the API dispatches, so providers come up before consumers and
+  `on_install` hooks run. Path-based installs keep the copy + reconcile
+  dev/test path.
