Import the MetaMesh app family from Worph/AppStore

23 apps (MetaCore, the library/network/client tiers and 13 MetaFeeder*)
move out of the general-purpose Worph/AppStore into their own store so the
MetaMesh family releases on its own cadence.

- asset URLs repointed to cdn.jsdelivr.net/gh/Worph/MetaAppStore@main
- store scaffolding added (category/recommend/featured lists, licence,
  contributing, gitattributes)
- psd-source/meta-icons-v2 icon generator follows the apps

MetaMCP stays in Worph/AppStore: it is third-party metatool-ai software,
not part of MetaMesh.

+
+## Repository Overview
+
+**MetaAppStore** is the CasaOS / Yundera 3rd-party app store for the **MetaMesh**
+application family only. It was split out of `Worph/AppStore` — the
+general-purpose fork — so the MetaMesh apps release on their own cadence. Apps
+that are *not* MetaMesh (Jellyfin, Nextcloud, MetaMCP — third-party
+`metatool-ai` software despite the name, …) stay in `Worph/AppStore` and must
+not be added here.
+
+⚠ **Asset URLs are repo-scoped.** Everything in this repo must reference
+`https://cdn.jsdelivr.net/gh/Worph/MetaAppStore@main/Apps/{AppName}/`. A file
+copied over from `Worph/AppStore` will carry the old
+`.../gh/Worph/AppStore@main/...` URL and its icon will silently 404 in the store
+listing. Grep after any import:
+
+```bash
+grep -rn 'gh/Worph/AppStore@main' Apps/   # must be empty
+```
+
+## Structure
+
+- `Apps/{AppName}/` — one dir per app:
+  - `docker-compose.yml` — compose + `x-casaos` metadata (the store entry)
+  - `icon.png`, `thumbnail.png`, `screenshot-{1,2,3}.png`
+  - optional `rationale.md`, `README.md`, `pre-install/`
+- `category-list.json` — only `Media` and `Developer` are used here
+- `recommend-list.json`, `featured-apps.json` — store front placement
+- `psd-source/meta-icons-v2/` — procedural icon generator for the family
+  (`gen_mesh.py` mesh sphere + `meta_icons.py` per-app badge); see its README
+
+## Conventions
+
+- **Storage**: `/DATA/AppData/{appname}/`; media under `/DATA/Media/`, `/DATA/Downloads/`
+- **Networking**: `expose`, not `ports`; main services join the external `pcs`
+  network for Caddy routing. Three caddy labels per public service:
+  `caddy_0` gateway domain (`appname-${APP_DOMAIN}`, `gateway_tls` import),
+  `caddy_1` nip.io, `caddy_2` sslip.io (Let's Encrypt, no import)
+- **`store_app_id`** is the lowercased app name (`MetaFeederTMDB` → `metafeedertmdb`)
+- **Images**: `ghcr.io/worph/meta*` pinned to `:latest` on purpose; the Yundera
+  perimeter images (`nginx-hash-lock`, `appshield`) stay version-pinned
+- **Install order**: `MetaCore` first — every other app depends on it
+- **Multi-language**: descriptions/taglines carry `en_us`, `fr_fr`, `es_es`, `zh_cn`, `ko_kr`, `de_de`
+
+## Cross-repo notes
+
+- Apps here are the deployable face of the services in `MetaMesh/meta-root-v2`;
+  this repo is vendored there as `packages/MetaAppStore`. A compose change made
+  directly on a box (e.g. `holyhorse`, `watch.nsl.sh`) is overwritten by a store
+  reinstall — port anything load-bearing back here.
+- Non-Meta companions live in `Worph/AppStore`: **Suwayomi** (chapter tier for
+  `MetaFeederSuwayomi`) and **SegmentPlayer**. Cross-references between the two
+  stores are prose-only; don't add hard dependencies.
+
+## Validation
+
+```bash
+docker compose -f Apps/{AppName}/docker-compose.yml config   # compose validity
+jq . category-list.json recommend-list.json featured-apps.json
+grep -rn 'gh/Worph/AppStore@main' Apps/                       # must be empty
+```
