simulator: CSI simulator with synthetic walkers and propagation model

- Implements full CSI simulator CLI at cmd/sim/
- Synthetic CSI frame generation using two-ray propagation model (direct + first-order reflection)
- Walker types: random-walk, path-following, node-to-node traversal
- User-defined paths via JSON file (--path-file)
- Wall attenuation with material properties (drywall, brick, concrete, glass, metal)
- BLE advertisement simulation (--ble flag)
- Ground truth CSV output with walker positions and per-link deltaRMS
- Scenario support: fall detection, OTA, bag-on-couch
- Blob count verification via --verify flag
- Seed-based reproducibility for deterministic tests
- Full test coverage (33 tests passing)
