feat (devcontainer): setup devcontainer for vscode

[johnnv1]

This pull request introduces a development container (devcontainer) setup for the project. The devcontainer configuration allows developers to have a consistent development environment using Visual Studio Code and Docker.

• Consistent Development Environment: Ensures all developers work in the same environment, reducing "it works on my machine" issues.
• Easy Setup: Simplifies the setup process for new contributors by providing a pre-configured development environment.
• Enhanced Tooling: Includes useful VSCode extensions and tools to improve productivity and code quality.

Changes

1. Devcontainer Configuration:

   • Added devcontainer.json file to define the development container settings.
   • The container uses the mcr.microsoft.com/devcontainers/rust:1-1 image, which includes Rust and its toolchain.

2. Post Create Command:

   • Added postCreateCommand.sh script to install additional dependencies and tools after the container is created.
   • The script installs cmake, nasm, libgstreamer1.0-dev, libgstreamer-plugins-base1.0-dev, Just command runner, and UV for managing Python virtual environments.

3. VSCode Customizations:

   • Configured VSCode extensions in the devcontainer.json to enhance the development experience:
     • rust-lang.rust-analyzer
     • streetsidesoftware.code-spell-checker
     • charliermarsh.ruff
     • Gruntfuggly.todo-tree
     • nefrob.vscode-just-syntax
