Initialize repository structure with Bazel build system and RST documentation

[Copilot]

Sets up foundational project structure for a Rust-based MP3 player learning project with modern Bazel build configuration.

Structure Created

• src/ - Rust source with initial main.rs entry point
• tests/ - Integration test skeleton
• docs/ - RST-format documentation (index.rst, architecture.rst)

Build System

• MODULE.bazel - Bazelmod configuration with rules_rust 0.48.0, edition 2021 (no legacy WORKSPACE)
• BUILD.bazel files for src/ and tests/ with rust_binary and rust_test targets
• .bazelversion - Pins to Bazel 8.4.2
• Updated .gitignore for Bazel artifacts

Usage

bazel build //src:rusty-mp3  # Build
bazel run //src:rusty-mp3    # Run
bazel test //tests:all        # Test

Documentation provides project overview, architecture principles, and planned components (MP3 parser, audio player, CLI).

Original prompt

Create some initial files to setup the basic repository structure. There shall be a src folder, a tests folder and there shall be a docs folder where documentation will be located.
Create an initial file structure to start building and testing the project, using Bazel (use bazelmod, no legacy WORKSPACE file). You can also add some initial documentation in .rst format. The project is an mp3 player, written in Rust for learning purposes.
