docs: Reorganize roadmap and TODO for passive sensing & multi-sensor phases

- Mark completed items in TODO
- Add v1.1 Passive Sensing & Multi-Sensor phase (probe capture,
  deauth detection, sensor ID, multi-sensor BLE correlation, alerting)
- Add v1.2 Profiling & Power Management phase
- Move on-device CSI processing to Future (lower priority)
- Add OSINT/purple team ideas (fingerprinting, triangulation, presence logging)

+## v1.1 - Passive Sensing & Multi-Sensor
+- [ ] Sensor ID in data packets (hostname prefix on all UDP streams)
+- [ ] WiFi probe request capture (`PROBE_DATA,<sensor>,<mac>,<rssi>,<ssid>`)
+- [ ] Deauth/disassoc frame detection (`ALERT_DATA,<sensor>,deauth,<mac>`)
+- [ ] Multi-sensor BLE correlation in esp-ctl (zone tracking by source sensor)
+- [ ] BLE alerting (known device list, alert on unknown MACs)
+- [ ] BLE dwell time tracking (loitering detection)
+- [ ] Timestamped CSV event logging
+
+## v1.2 - Profiling & Power Management
+- [x] PROFILE command (heap, stack watermarks, CPU runtime stats)
+- [ ] Chip temperature reporting in STATUS
+- [ ] Power consumption measurements (per-mode baseline)
+- [ ] Deep sleep mode with wake-on-CSI-motion
+- [ ] Battery-optimized duty cycling

 ## Future
-- WiFi probe request capture (promiscuous mode, WIFI_PKT_MGMT)
-  - Capture client SSID searches → `PROBE_DATA,<mac>,<rssi>,<ssid>` via UDP
-  - Uses `esp_wifi_set_promiscuous` with management frame filter
-  - Can coexist with CSI (both use promiscuous callbacks)
-- AP+STA config portal (WIFI_MODE_APSTA, same channel as STA)
-  - Soft-AP for initial setup: WiFi credentials, UDP target IP, hostname
-  - Captive portal or minimal HTTP server on AP interface
-  - Eliminates need for hardcoded config in sdkconfig
+- AP+STA config portal (WIFI_MODE_APSTA, captive portal for initial setup)
 - ESP-NOW mesh (ESP32-to-ESP32 CSI)
-- Multi-channel scanning
+- Multi-channel scanning (hop across WiFi channels)
+- RSSI triangulation with 3 sensors (approximate device location)
+- BLE device fingerprinting (identify phone models by advertisement patterns)
+- Historical presence logging (who was here, when, how long)
 - External sensor support (PIR, temp/humidity via GPIO)
-- Power management for battery operation
+- On-device CSI processing (send metrics, not raw)
