Feature: Add DeepFilterCommandBuilder to MediaProcessor

[omeryusufyagci]

Implement a DeepFilterCommandBuilder class to establish a high-level API for constructing DeepFilterNet commands, extending the CommandBuilder base class. Methods such as setInputAudio() and setNoiseReductionLevel() should abstract the command details.

This will make the filtering process more maintainable and user-friendly, eliminating the need for users to understand command-level specifics. Will be needed by the frontend for v1.0.s

DeepFilterCommandBuilder cmd;
cmd.setInputAudio(inputAudioPath);
cmd.setOutputAudio(outputAudioPath);
cmd.setNoiseReductionLevel(0.5);
// ...

See discussion in #4 for more context.

A good first issue as it's a direct extension of an existing class, requiring minimal understanding of the full project.
