This pull request removes all benchmark-related files and documentation from the STYLY-NetSync-Server/benchmark directory. The changes eliminate the Locust-based benchmarking tools, their configuration, client abstractions, and supporting documentation, effectively deprecating the benchmark component from the repository.

Removal of benchmark source code and configuration:

• Deleted src/benchmark_config.py, src/client_factory.py, src/clients/client_interface.py, and all __init__.py files, removing all core logic for benchmark configuration, client creation, and interface definitions. [1] [2] [3] [4] [5]
• Removed pyproject.toml and .python-version, eliminating Python package configuration and version pinning for the benchmark module. [1] [2]
