feat(rvcsi): rvcsi-runtime composition + rvcsi-node (napi-rs) + rvcsi-cli + @ruv/rvcsi TS SDK

- rvcsi-runtime — the composition layer (no FFI): CaptureRuntime (CsiSource +
  validate_frame + SignalPipeline + EventPipeline, with next_validated_frame /
  next_clean_frame / drain_events / health) plus one-shot helpers
  (summarize_capture → CaptureSummary, decode_nexmon_records, events_from_capture,
  export_capture_to_rf_memory, rf_memory_self_check). 10 tests.
- rvcsi-node — the napi-rs seam (cdylib+rlib, build.rs runs napi_build::setup):
  thin #[napi] wrappers over rvcsi-runtime — rvcsiVersion / nexmonShimAbiVersion /
  nexmonDecodeRecords / inspectCaptureFile / eventsFromCaptureFile /
  exportCaptureToRfMemory + an RvcsiRuntime streaming class. Everything that
  crosses the boundary is a validated/normalized rvCSI struct serialized to JSON
  (D6). deny(clippy::all).
- @ruv/rvcsi npm package (package.json + index.js + index.d.ts + README +
  __test__/api.test.cjs) — curated JS surface that JSON-parses the addon's
  output into plain CsiFrame/CsiWindow/CsiEvent/SourceHealth/CaptureSummary
  objects; lazy native-addon load with a helpful "not built" error.
- rvcsi-cli — the `rvcsi` binary: record (Nexmon dump → .rvcsi, validating),
  inspect, replay, stream, events, health, calibrate (v0 baseline), export
  ruvector. 7 tests exercising every subcommand against in-memory captures.
- rvcsi-cli no longer depends on rvcsi-node (a binary can't link the napi addon);
  the shared logic moved to rvcsi-runtime. .gitignore: ignore the generated
  *.node / binding.js / binding.d.ts / npm/ under rvcsi-node.

All rvcsi crates: build together OK, clippy-clean, 140 unit/integration tests +
2 doctests, 0 failures (core 29, dsp 28, events 18, adapter-file 20+1,
adapter-nexmon 9, ruvector 20+1, runtime 10, cli 7).
