.devcontainer/devcontainer.json is a non-functional one-line stub

[N-thnI]

Problem

.devcontainer/devcontainer.json is a one-line stub ({"name": "Soroban Environment"}) with no base image, features, extensions, or postCreateCommand declared.

Why it matters

The file's presence implies a working devcontainer setup, but opening this repo in a devcontainer-aware editor wouldn't actually install Rust, the wasm32-unknown-unknown target, or soroban-cli — it silently fails to deliver the environment its name promises.

Suggested fix

Flesh out devcontainer.json with a real base image (or Dockerfile) plus postCreateCommand/features that install the Rust toolchain, wasm32-unknown-unknown target, and soroban-cli, matching what CONTRIBUTING.md/DEPLOY.md describe as the required local setup.

Acceptance criteria

• Opening the repo in a devcontainer produces a working Rust + Soroban toolchain without manual setup
• devcontainer.json declares a concrete base image and setup steps
