post-1.0: expose PreparedQuery over UniFFI #181
Description
Roadmap source
ROADMAP.md: Phase 8.2, "Post-1.0 FFI deferrals".
Work item
Expose prepare() / PreparedQuery through the UniFFI-based bindings.
Context
Prepared statements require a stateful handle and bind-slot substitution across the FFI boundary. The design was deferred until the basic FFI API had proven stable.
Acceptance criteria
- Add a stable FFI handle for prepared queries.
- Support the existing bind value types exposed by Rust prepared statements.
- Add FFI tests covering repeated execution with different bindings.
- Document handle ownership and error behavior.
