Two-crate workspace: immo-core for pure financial logic (wasm-compatible,
no async/IO deps) and immo-web for HTTP and rendering. Both crates are
still cargo-new skeletons; no domain code yet.
Pins the toolchain to 1.97 with rustfmt, clippy and the
wasm32-unknown-unknown target so the core crate's wasm constraint is
checkable locally. Cargo.lock is committed since the workspace ships a
binary.
