feat: complete vendor repos, add edge intelligence and WASM modules

- Add 154 missing vendor files (gitignore was filtering them) - vendor/midstream: 564 files (was 561) - vendor/sublinear-time-solver: 1190 files (was 1039) - Add ESP32 edge processing (ADR-039): presence, vitals, fall detection - Add WASM programmable sensing (ADR-040/041) with wasm3 runtime - Add firmware CI workflow (.github/workflows/firmware-ci.yml) - Add wifi-densepose-wasm-edge crate for edge WASM modules - Update sensing server, provision.py, UI components Co-Authored-By: claude-flow <ruv@ruv.net>

+# WASM3 — WebAssembly interpreter for ESP-IDF
+#
+# ADR-040: Tier 3 WASM programmable sensing layer.
+# WASM3 is an MIT-licensed, lightweight interpreter (~100 KB flash, ~10 KB RAM)
+# optimized for embedded targets including Xtensa ESP32-S3.
+#
+# Pre-download WASM3 source before building:
+#   cd firmware/esp32-csi-node/components/wasm3
+#   git clone --depth 1 https://github.com/wasm3/wasm3.git wasm3-src
+#
+# Or run: scripts/fetch-wasm3.sh
