chore: bump workspace to v0.3.0 and publish 15 crates to crates.io

- Workspace version: 0.2.0 → 0.3.0
- All internal path dependency versions updated
- ruvector-crv/gnn gated behind optional `crv` feature (removed [patch.crates-io])
- All 15 crates published to crates.io at v0.3.0

Published crates (in order):
  1. wifi-densepose-core
  2. wifi-densepose-vitals
  3. wifi-densepose-wifiscan
  4. wifi-densepose-hardware
  5. wifi-densepose-config
  6. wifi-densepose-db
  7. wifi-densepose-signal
  8. wifi-densepose-nn
  9. wifi-densepose-ruvector
  10. wifi-densepose-api
  11. wifi-densepose-train
  12. wifi-densepose-mat
  13. wifi-densepose-wasm
  14. wifi-densepose-sensing-server
  15. wifi-densepose-cli
