feat: ADR-069 ESP32 CSI → Cognitum Seed RVF pipeline (v0.5.4-esp32)

Hardware-validated pipeline connecting ESP32-S3 CSI sensing to Cognitum
Seed (Pi Zero 2 W) edge intelligence appliance via 8-dim feature vectors.

Firmware:
- New 48-byte feature vector packet (magic 0xC5110003) at 1 Hz with
  normalized presence, motion, breathing, heart rate, phase variance,
  person count, fall detection, and RSSI
- Compressed frame magic reassigned 0xC5110003 → 0xC5110005
- Guard against uninitialized s_top_k read when count=0

Bridge (scripts/seed_csi_bridge.py):
- UDP→HTTPS ingest with bearer token, hash-based vector IDs
- --validate (kNN), --stats, --compact, --allowed-sources modes
- NaN/inf rejection, retry logic, SEED_TOKEN env var support

Validated on live hardware:
- 941 vectors ingested, 100% kNN exact match
- Witness chain SHA-256 verified (1,325 entries)
- 1,463 Rust tests passed, Python proof VERDICT: PASS

Research: 26 docs covering Arena Physica, Maxwell's equations in WiFi
sensing, SOTA survey 2025-2026, GOAP implementation plan

Security: removed hardcoded credentials, added NVS patterns to
.gitignore, source IP filtering, NaN validation

+ADR-069: ESP32 CSI → Cognitum Seed RVF Ingest Bridge
+
+Listens for CSI feature vectors from ESP32 nodes via UDP, batches them,
+and ingests into the Cognitum Seed's RVF vector store via HTTPS REST API.
+
+Usage:
+    # Run bridge (default mode)
+    python scripts/seed_csi_bridge.py \
+        --seed-url https://169.254.42.1:8443 \
+        --token "$SEED_TOKEN" \
+        --udp-port 5006 \
+        --batch-size 10
+
+    # Run with validation (kNN query + PIR comparison after each batch)
+    python scripts/seed_csi_bridge.py \
+        --token TOKEN --validate
+
+    # Print Seed stats
+    python scripts/seed_csi_bridge.py --token TOKEN --stats
+
+    # Trigger store compaction
+    python scripts/seed_csi_bridge.py --token TOKEN --compact
+
+The bridge also accepts legacy ADR-018 CSI frames (magic 0xC5110001/0xC5110002)
+and extracts a simplified 8-dim feature vector from the raw data.
