docs: Update README.md with detailed documentation
This commit significantly enhances the `README.md` file, providing comprehensive documentation for the ArmaDragonflyClient.

Key changes:

*   **Detailed Function Categories:** Categorized functions for better organization (Core, Basic Data Operations, Hash Operations, List Operations).
*   **Usage Examples:** Added clear and concise usage examples for basic operations, hash operations (context and ID-specific), and list operations.
*   **Function Documentation Structure:** Outlined the structure for individual function documentation.
*   **License Information:** Updated the license information.

# dragonfly_db_fnc_handler
## Description
Handles data received from the database and routes it to the appropriate function. This function is a critical component of the callback system, receiving data from database operations and directing it to the specified function, either locally or to a remote client.
## Syntax
```sqf
[_uniqueID, _function, _call, _data, _netId] call dragonfly_db_fnc_handler
```
## Parameters
| Parameter | Type | Description | Default |
|-------------|----------------------------------|-------------------------------------------------------|---------|
| `_uniqueID` | String | Unique identifier for the data chunk | "" |
| `_function` | String | Name of function to receive the data | "" |
| `_call` | Boolean | Whether to call the function directly (true) or spawn (false) | false |
| `_data` | Array, String, Number, or Boolean| The data retrieved from the database | [] |
| `_netId` | String | (Optional) NetID of the player to receive the data | nil |
## Return Value
None. The data is passed to the specified function for processing.
## Examples
### Process data locally:
```sqf
["0123456789", "dragonfly_db_fnc_test", false, ["Hello World!"]] call dragonfly_db_fnc_handler;
```
### Send data to a specific client:
```sqf
["0123456789", "dragonfly_db_fnc_test", false, ["Hello World!"], netId player] remoteExecCall ["dragonfly_db_fnc_handler", 2, false];
```
### Process data with direct call (synchronous):
```sqf
["0123456789", "dragonfly_db_fnc_processInventory", true, [["weapon1", 30], ["item2", 5]]] call dragonfly_db_fnc_handler;
```
## Notes
- The function validates that both the function name and data are valid before proceeding
- When a netId is provided, the data is sent to that specific client using remoteExec
- The `_call` parameter determines whether the function is called directly (synchronous) or spawned (asynchronous)
- This function is typically called by the scheduler or other core components rather than directly by user code
- Each handler call is logged, which is useful for debugging data flow
