feat: auto-create custom fields, add try/catch coverage, PHPDoc, and Pint formatting

- Auto-create 'Initial Operating System' and 'Initial SSH Key' custom fields
  via Database::ensureCustomFields() on module load, eliminating the manual
  modify.sql step
- Delete modify.sql (no longer needed)
- Add try/catch blocks around every DB operation and API call across all PHP
  files per CLAUDE.md error handling rules
- Add comprehensive PHPDoc to all classes, methods, and properties
- Set up Laravel Pint (laravel/pint) with Laravel-style preset for consistent
  code formatting across the codebase
- Add git pre-commit hook (hooks/pre-commit) that runs Pint on staged PHP
  files, auto-installed via Composer post-install/post-update scripts
- Simplify README installation to a single copy-paste command

 ### Configurable Option Mapping
 
 Custom option names can be mapped in `config/ConfigOptionMapping.php` (copy from `-example.php`). Default mapping keys: `packageId`, `hypervisorId`, `ipv4`, `storage`, `memory`, `traffic`, `cpuCores`, `networkSpeedInbound`, `networkSpeedOutbound`, `networkProfile`, `storageProfile`.

 ## Installation
 
-### Step 1: Download & Install
-
-Download the latest release from the [releases](https://github.com/EZSCALE/virtfusion-whmcs-module/releases) page, or install directly via the command line:
-
 ```bash
-cd /tmp
+git clone https://github.com/EZSCALE/virtfusion-whmcs-module.git /tmp/vf && rsync -ahP --delete /tmp/vf/modules/servers/VirtFusionDirect/ /path/to/whmcs/modules/servers/VirtFusionDirect/ && rm -rf /tmp/vf

-rsync -ahP --delete /tmp/virtfusion-whmcs-module/modules/servers/VirtFusionDirect/ /path/to/whmcs/modules/servers/VirtFusionDirect/

-The resulting file structure should be:
+Then configure in WHMCS Admin:
 
-```
+1. **Add Server** — Configuration > System Settings > Servers > Add New Server. Set hostname to your VirtFusion panel (e.g. `cp.example.com`), type to "VirtFusion Direct Provisioning", and paste your API token in the Password field. Click **Test Connection** to verify.
-modules/servers/VirtFusionDirect/
+2. **Create Product** — Configuration > System Settings > Products/Services. On the Module Settings tab, select "VirtFusion Direct Provisioning", choose your server, and set the Hypervisor Group ID, Package ID, and Default IPv4 count.

-### Step 2: Set Up Server in WHMCS
+That's it. Hooks activate automatically and custom fields are created on module load.
-
-1. Go to **Configuration > System Settings > Servers**
-2. Click **Add New Server**
-3. Fill in:
-   - **Name**: Anything descriptive (e.g., "VirtFusion Production")
-   - **Hostname**: Your VirtFusion panel hostname (e.g., `cp.example.com`)
-   - **Type**: VirtFusion Direct Provisioning
-   - **Password/Access Hash**: Your VirtFusion API token
-4. Click **Test Connection** to verify
-5. Click **Save Changes**
-
-### Step 3: Create Product
-
-1. Go to **Configuration > System Settings > Products/Services**
-2. Create a new product or edit an existing one
-3. On the **Module Settings** tab:
-   - Set **Module Name** to "VirtFusion Direct Provisioning"
-   - Select your VirtFusion server
-   - Set **Hypervisor Group ID**, **Package ID**, and **Default IPv4** count
-4. Save the product
-
-### Step 4: Set Up Custom Fields
-
-See [Custom Fields](#custom-fields) section below.
-
-### Step 5: Activate Hooks
-
-The hooks file (`hooks.php`) is automatically detected by WHMCS when the module is active. If you add the module files to an existing installation, you may need to re-save the product settings or clear the WHMCS template cache for hooks to take effect.
 
 ## Upgrading
 
-1. Back up your existing `modules/servers/VirtFusionDirect/` directory
-2. Back up `config/ConfigOptionMapping.php` if you have a custom mapping
-3. Download and deploy the new version:
-
 ```bash
-cd /tmp
+git clone https://github.com/EZSCALE/virtfusion-whmcs-module.git /tmp/vf && rsync -ahP --delete /tmp/vf/modules/servers/VirtFusionDirect/ /path/to/whmcs/modules/servers/VirtFusionDirect/ && rm -rf /tmp/vf
-git clone https://github.com/EZSCALE/virtfusion-whmcs-module.git
-rsync -ahP --delete /tmp/virtfusion-whmcs-module/modules/servers/VirtFusionDirect/ /path/to/whmcs/modules/servers/VirtFusionDirect/
-rm -rf /tmp/virtfusion-whmcs-module
 ```
 
-4. Restore your custom `config/ConfigOptionMapping.php` if applicable
+> **Note:** If you have a custom `config/ConfigOptionMapping.php`, back it up first — `--delete` will remove it. Restore it after upgrading.
-5. If you have theme-overridden templates, review them for any new template variables
-6. Clear the WHMCS template cache: **Configuration > System Settings > General Settings > clear template cache**
 
-The module database table (`mod_virtfusion_direct`) is automatically migrated on first load.
+If you use theme-overridden templates, review them for any new template variables. Clear the WHMCS template cache after upgrading: **Configuration > System Settings > General Settings > clear template cache**.
