Mike-Solar e1423553c7 refactor(engine): single-lib phase 1 — direct Rust calls across the facade
- unify CHandle in oakcore-rs (all crates re-export it)
- facade bridge: 618/624 externs converted to direct module calls
- signature-drift fixes surfaced by direct calls (videoparams,
  seconds, sync estimate, POD unification)
- dead node<->render call sites removed; cancelatom -> oakcommon
- node bridge/undo -> oakundo direct calls
- docs/zh/plans/riir/single-lib.md: design + live status
