02-tekhnohim: add LAN TeleProxy over Xray Reality stack

Add a dedicated Git-managed stack that leaves the existing Nginx Proxy Manager bindings on ports 80/443 unchanged and publishes the Telegram endpoint only on 192.168.0.35:10443.\n\nTeleProxy direct-mode traffic is routed through an isolated Xray SOCKS5 client and the dedicated Hetzner VLESS+Reality egress at 89.167.72.79:443. Both upstream images are digest-pinned. Credential-bearing Xray and TeleProxy files remain root-controlled host files under /mnt/containers/telegram-reality and are explicitly excluded from Git.

+# Telegram proxy through Xray Reality
+
+This stack publishes TeleProxy only on the client LAN:
+
+- client endpoint: `192.168.0.35:10443/tcp`;
+- TeleProxy runs in direct mode;
+- Telegram DC traffic goes to the local Xray SOCKS5 client;
+- Xray sends the outbound leg through the dedicated Hetzner VLESS+Reality
+  server at `89.167.72.79:443`;
+- Nginx Proxy Manager keeps exclusive ownership of host ports `80` and `443`.
+
+The stack deliberately keeps credential-bearing files outside Git:
+
+| Host path | Purpose | Required mode |
+|---|---|---|
+| `/mnt/containers/telegram-reality/xray-client.json` | Xray Reality client credentials and local SOCKS inbound | `0600`, owner `65532:65532` |
+| `/mnt/containers/telegram-reality/teleproxy.env` | TeleProxy secret and label | `0600`, owner `root:root` |
+| `/mnt/containers/telegram-reality/teleproxy-link.txt` | Generated LAN-only Telegram connection link | `0600`, owner `root:root` |
+
+Deploy this directory as a Portainer Git stack named `telegram-reality`, or run
+it with Docker Compose using project name `telegram-reality`. The absolute
+configuration files must already exist on the host before deployment.
