Mike-Solar 431b9ed2b1 feat(oakrender): render-process isolation S1 - dispatcher, scheduler, real worker
Per the M15 design (docs/zh/plans/riir/M15-render-process-isolation.md):

- ipc.rs moved into oakrender with protocol v2: hello_caps,
  render_batch, batch_accepted, frame_failed; main-process-assigned
  slots; BGRA8 slot format. POSIX shm verified to 1GiB on macOS.
- ProcessDispatcher: spawns oak-worker processes, handshake, stdio
  NDJSON control, shm segment lifecycle with generation-tagged keys,
  crash detection with bounded restart and frame redispatch, zero-copy
  ShmFrameRef delivery and copy counters.
- PreviewScheduler: interleaved batch claiming (frame % W per worker,
  no work stealing), seek > playback-distance > background priority,
  credit-based flow control, crash recovery.
- oak-worker renders for real: graph snapshot deserialization, montage
  decode+composite straight into the assigned shm slot, F32->BGRA8
  final conversion in-worker, OFX plugin executor installed in-worker,
  crash hooks for isolation testing.

Thread pool coexists for now (S2 removes it). Integration tests cover
two-worker zero-copy rendering, crash isolation with redelivery, and
real H.264 footage decode into slots.

//! Render-worker IPC shim (M15 S1): the NDJSON protocol and the
//! shared-memory frame-slot transport now live in the oakrender crate
//! (`oakrender::ipc`) so both ends of the pipe link one copy — the
//! main-process dispatcher creates the segments and the worker attaches
//! to them. This module re-exports the whole surface, keeping the
//! worker-side `crate::ipc::` paths unchanged. The facade (oakengine)
//! still keeps its own copy for the frozen `oakengine_ipc_*` C ABI.
