Set up cargo workspace backbone 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

[dependencies]
Add Euros money type backed by integer cents Store amounts as i64 cents rather than a Decimal, so the "scale is 2" invariant is structural instead of maintained by hand. Both accessors are total: as_cents is a field read, as_decimal derives the Decimal on demand. i64 rather than u64 because differences between amounts can be negative. Add rust_decimal, verified to build for wasm32-unknown-unknown with default features. Allow clippy::inconsistent_digit_grouping in immo-core so cent literals can be grouped as euros-then-cents.

Add LoanOffer with validating constructor LoanOffer::new is the only way in: fields are private and the constructor rejects a negative rate, a zero duration, and a non-positive capital. A zero rate is accepted on purpose — the PTZ (prêt à taux zéro) is a real French instrument. Add thiserror for the typed error, as required for immo-core. Rate and duration take no upper bound for now. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
