Add rust-analyzer setup for Bazel and VS Code tasks

[ShoroukRamzy]

Added instructions in the README.md for generating the rust-project.json file required by rust-analyzer in a Bazel workflow. Also included a .vscode/tasks.json to easily automate this generation and updated .vscode/settings.json to explicitly point rust-analyzer to the generated Bazel project config, ensuring Cargo does not conflict.
This will significantly improve the IDE onboarding experience for new developers.
