This commit introduces the `DefDestructure` bound kind and modifies the binder, analyzer, type checker, and VM to support destructuring in `def` statements. This allows for pattern matching on the right-hand side of a `def` to bind multiple variables. The parser has been updated to accept patterns in `def` statements. The binder now handles `UntypedKind::Def` with a `target` pattern, rather than a simple `name`. This enables destructuring. The `Gemini.md` documentation has been updated to include a new rule for incremental development.
