feat(cli): allow runner configuration to be an object with cwd and args

[mhbagheri-99]

This PR implements the feature requested in #13779 to allow the "runner" configuration in tauri.conf.json to be either a string (existing behavior) or an object with additional properties.

Changes

• Enhanced the runner configuration to support an object format with the following properties:
  • cmd: The command to execute (equivalent to the previous string format)
  • cwd: Optional working directory to run the command from
  • args: Optional array of arguments to pass to the runner

Example Usage

The runner can now be configured as an object:

{
  "build": {
    "runner": {
      "cmd": "my_custom_cargo",
      "cwd": "/path/to/project",
      "args": ["--quiet", "--offline"]
    }
  }
}

Or continue using the existing string format for backwards compatibility:

{
  "build": {
    "runner": "cargo"
  }
}

Backwards Compatibility

This change maintains full backwards compatibility - existing configurations using a string for the runner will continue to work as before.

Closes #13779
