## HexHub Server Feed Update

### Added
- Added a new server-owned HexHub feed shared with every connected player.
- Added three selectable feed modes:
  - Normal — reads the official remote GitHub feed.
  - Client — reads the player's local `hub_client.json`.
  - Server — requests the dedicated server's shared feed.
- Added client/server packet synchronization for the Server Feed.
- Added automatic generation of:

`config/hexcolortext/hub_server_feed.json`

- Added new server commands:

`/hexhubserver path`

`/hexhubserver reload`

### Improved
- Preserved the custom textured HexHub feed toggle button.
- Normal Feed now attempts to read the official remote JSON first.
- Local and built-in entries are only used as fallbacks if the remote feed cannot be loaded.
- Server Feed entries support HexText and HyperText formatting, including gradients, shadows, glows, scrolling colors, styled tags, and styled tag backgrounds.
- Server owners can update announcements without rebuilding the mod.
- Running `/hexhubserver reload` reloads the server JSON and synchronizes the updated feed with connected players.

### Feed Order

`Normal → Client → Server → Normal`

### Server Setup
After installing the update, restart the server once to generate:

`config/hexcolortext/hub_server_feed.json`

Edit the generated JSON, save it, and run:

`/hexhubserver reload`

Players can then select Server Feed inside HexHub to view the updated server announcements.
