Update contribution docs for fork setup and metadata

Revised documentation to standardize use of 'bash docs/contribution/setup-fork.sh --full' for fork configuration, clarified install script execution flow, and updated JSON metadata template and field references. Improved helper function docs, resource requirements, and category lists. Updated references and instructions throughout for consistency and accuracy.

+# 🧪 Code Audit: LXC Script Flow
 
-1) [adguard.sh](https://github.com/community-scripts/ProxmoxVE/blob/main/ct/adguard.sh): This script collects system parameters. (Also holds the function to update the application.)
-2) [build.func](https://github.com/community-scripts/ProxmoxVE/blob/main/misc/build.func): Adds user settings and integrates collected information.
-3) [create_lxc.sh](https://github.com/community-scripts/ProxmoxVE/blob/main/misc/create_lxc.sh): Constructs the LXC container.
-4) [adguard-install.sh](https://github.com/community-scripts/ProxmoxVE/blob/main/install/adguard-install.sh): Executes functions from [install.func](https://github.com/community-scripts/ProxmoxVE/blob/main/misc/install.func), and installs the application.
-5) [adguard.sh](https://github.com/community-scripts/ProxmoxVE/blob/main/ct/adguard.sh) (again): To display the completion message.
+This guide explains the current execution flow and what to verify during reviews.
 
-The installation process uses reusable scripts: [build.func](https://github.com/community-scripts/ProxmoxVE/blob/main/misc/build.func), [create_lxc.sh](https://github.com/community-scripts/ProxmoxVE/blob/main/misc/create_lxc.sh), and [install.func](https://github.com/community-scripts/ProxmoxVE/blob/main/misc/install.func), which are not specific to any particular application.
+## Execution Flow (CT + Install)
 
-To gain a better understanding, focus on reviewing [adguard-install.sh](https://github.com/community-scripts/ProxmoxVE/blob/main/install/adguard-install.sh). This script contains the commands and configurations for installing and configuring AdGuard Home within the LXC container.
+1. `ct/appname.sh` runs on the Proxmox host and sources `misc/build.func`.
+2. `build.func` orchestrates prompts, container creation, and invokes the install script.
+3. Inside the container, `misc/install.func` exposes helper functions via `$FUNCTIONS_FILE_PATH`.
+4. `install/appname-install.sh` performs the application install.
+5. The CT script prints the completion message.
+
+## Audit Checklist
+
+### CT Script (ct/)
+
+- Sources `misc/build.func` from `community-scripts/ProxmoxVE/main` (setup-fork.sh updates for forks).
+- Uses `check_for_gh_release` + `fetch_and_deploy_gh_release` for updates.
+- No Docker-based installs.
+
+### Install Script (install/)
+
+- Sources `$FUNCTIONS_FILE_PATH`.
+- Uses `tools.func` helpers (setup\_\*).
+- Ends with `motd_ssh`, `customize`, `cleanup_lxc`.
+
+### JSON Metadata
+
+- File in `frontend/public/json/<appname>.json` matches template schema.
+
+### Testing
+
+- Test via curl from your fork (CT script only).
+- Wait 10-30 seconds after push.
