devcontainer.json

// DevFlow dev container: pinned Rust toolchain matching rust-toolchain.toml
// (an exact version, never a floating channel; components clippy and rustfmt),
// with cargo registry and workspace target/ caches persisted across rebuilds.
// Base image tag verified against mcr.microsoft.com/v2/devcontainers/rust/tags/list
// (current published bookworm tag as of 2026-07-17) — pin deliberately; never use
// an unversioned floating tag.
