feat: WiFi mesh handoff - seamless AP roaming (Issue #458)

Add WiFi mesh handoff infrastructure:

WiFiState.msg interface:
- SSID, signal strength (dBm), connection status
- AP address, frequency, link quality
- TX/RX rates, roaming flag
- Available APs for handoff decision

WiFi Monitor Node:
- Signal monitoring via iwconfig/nmcli
- Auto-roam at -70dBm threshold
- Seamless wpa_supplicant roaming
- Gateway ping (8.8.8.8) every 5s
- USB tethering fallback if offline >30s
- TTS warnings for connectivity issues
- Coverage logging with AP transitions

Features:
- Configurable roaming threshold (-70dBm default)
- Gateway connectivity verification
- Offline detection with configurable timeout
- USB tethering auto-activation/deactivation
- Signal strength change logging (>5dBm)
- AP transition logging
- Manual rescan/tether control commands

Topics:
- /saltybot/wifi_state (String)
- /saltybot/speech_text (String warnings)
- /saltybot/wifi_cmd (String commands)

Configuration:
- interface: wlan0
- roam_threshold_dbm: -70
- offline_warning_timeout: 30.0
- target_ssid: SaltyLab
- fallback_tether: true
- coverage_log_file: /tmp/wifi_coverage.log

Roaming Behavior:
- Monitors signal continuously
- When signal < -70dBm, scans for stronger AP
- wpa_supplicant performs seamless handoff
- Logs all AP transitions to coverage file

Fallback Behavior:
- Pings gateway every 5 seconds
- If unreachable for >30s, activates USB tether
- TTS alert: 'Warning: Lost WiFi connectivity...'
- Auto-deactivates when WiFi restored

Coverage Mapping:
- Logs timestamp, SSID, signal, connected status
- Tracks roaming events
- Useful for mesh network optimization

+# SaltyBot WiFi Mesh Handoff (Issue #458)
+
+Seamless WiFi AP roaming with automatic fallback to USB tethering.
+
+## Features
+
+- **Signal Monitoring**: Continuous WiFi signal strength tracking via iwconfig
+- **Auto-Roaming**: Seamless handoff to stronger AP when signal < -70dBm
+- **Gateway Ping**: Periodic connectivity verification to 8.8.8.8
+- **USB Tethering Fallback**: Auto-activate phone USB tether if WiFi offline >30s
+- **TTS Warnings**: Voice alerts for connectivity issues
+- **Coverage Mapping**: Logs all signal transitions for analysis
+- **wpa_supplicant Integration**: Native WiFi roaming support
+- **Status Publishing**: Real-time WiFi state on `/saltybot/wifi_state`
+
+## Setup
+
+### 1. WiFi Configuration
+
+Edit `/etc/wpa_supplicant/wpa_supplicant.conf`:
+
+```
+network={
+  ssid="SaltyLab"
+  psk="password"
+  bgscan="simple:30:-70:600"
+  ap_scan=1
+  priority=10
+}
+```
+
+### 2. Launch
+
+```bash
+ros2 launch saltybot_wifi_monitor wifi_monitor.launch.py
+```
+
+### 3. Monitor
+
+```bash
+ros2 topic echo /saltybot/wifi_state
+```
+
+## Configuration
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `interface` | wlan0 | WiFi interface |
+| `roam_threshold_dbm` | -70 | Roaming signal threshold |
+| `offline_warning_timeout` | 30.0 | Timeout before USB fallback |
+| `target_ssid` | SaltyLab | Target mesh SSID |
+| `fallback_tether` | true | Enable USB tethering |
+
+## Roaming Behavior
+
+Automatic roaming when:
+1. Signal < -70dBm
+2. Stronger AP available (>5dBm better)
+3. wpa_supplicant performs seamless handoff
+4. No ROS message disruption
+
+## Fallback Behavior
+
+Automatic fallback when:
+1. Gateway ping fails for >30 seconds
+2. TTS warning published
+3. USB tethering activated
+4. Auto-deactivated when WiFi restored
+
+## Topics
+
+| Topic | Type | Description |
+|-------|------|-------------|
+| `/saltybot/wifi_state` | String | Current WiFi state |
+| `/saltybot/speech_text` | String | TTS warnings |
+| `/saltybot/wifi_cmd` | String | Control commands |
+
+## Coverage Log
+
+```bash
+tail -f /tmp/wifi_coverage.log
+```
+
+Output:
+```
+2026-03-05T09:15:23.456 | SSID:SaltyLab | Signal:-65dBm | Connected:true | Roaming:false
+2026-03-05T09:15:45.789 | SSID:SaltyLab-5G | Signal:-62dBm | Connected:true | Roaming:true
+```
+
+## Issue #458 Completion
+
+✅ WiFi signal monitoring (iwconfig/nmcli)
+✅ WiFiState.msg interface
+✅ Auto-roam at -70dBm
+✅ Seamless wpa_supplicant handoff
+✅ Gateway ping verification
+✅ USB tethering fallback
+✅ TTS warnings (offline >30s)
+✅ Coverage logging + AP transitions
+✅ Configurable parameters
+✅ Manual control commands
