feat: Add Space Weather mode with real-time solar and geomagnetic monitoring

New mode providing real-time space weather data from NOAA SWPC, NASA SDO,
and HamQSL APIs. Includes Kp index, solar wind, X-ray flux charts, HF band
conditions, D-RAP absorption maps, aurora forecast, solar imagery, flare
probability, and active solar regions. No SDR hardware required.

Bumps version to 2.20.0. Updates all documentation including README, FEATURES,
USAGE, UI_GUIDE, help modal, and GitHub Pages site.

 ## Project Overview
 
-INTERCEPT is a web-based Signal Intelligence (SIGINT) platform providing a unified Flask interface for software-defined radio (SDR) tools. It supports pager decoding, 433MHz sensors, ADS-B aircraft tracking, ACARS messaging, WiFi/Bluetooth scanning, and satellite tracking.
+INTERCEPT is a web-based Signal Intelligence (SIGINT) platform providing a unified Flask interface for software-defined radio (SDR) tools. It supports pager decoding, 433MHz sensors, ADS-B aircraft tracking, ACARS messaging, WiFi/Bluetooth scanning, satellite tracking, ISS SSTV decoding, AIS vessel tracking, weather satellite imagery (NOAA APT & Meteor LRPT), and Meshtastic mesh networking.

+#### Multi-Architecture Builds (amd64 + arm64)
+
+Cross-compile on an x64 machine and push to a registry. This is much faster than building natively on an RPi.
+
+```bash
+# One-time setup on your x64 build machine
+docker run --privileged --rm tonistiigi/binfmt --install all
+docker buildx create --name intercept-builder --use --bootstrap
+
+# Build and push for both architectures
+REGISTRY=ghcr.io/youruser ./build-multiarch.sh --push
+
+# On the RPi5, just pull and run
+INTERCEPT_IMAGE=ghcr.io/youruser/intercept:latest docker compose --profile basic up -d
+```
+
+Build script options:
+
+| Flag | Description |
+|------|-------------|
+| `--push` | Push to container registry |
+| `--load` | Load into local Docker (single platform only) |
+| `--arm64-only` | Build arm64 only (for RPi deployment) |
+| `--amd64-only` | Build amd64 only |
+
+Environment variables: `REGISTRY`, `IMAGE_NAME`, `IMAGE_TAG`
+
+#### Using a Pre-built Image
+
+If you've pushed to a registry, you can skip building entirely on the target machine:
+
+```bash
+# Set in .env or export
+INTERCEPT_IMAGE=ghcr.io/youruser/intercept:latest
+
+# Then just run
+docker compose --profile basic up -d

+1. **Start GPS** - Click "Start" to connect to gpsd and begin position tracking
+2. **View Map** - Your position appears on the interactive map with a track trail
+3. **Monitor Stats** - Speed, heading, altitude, and satellite count displayed in real-time
+4. **Record Track** - Enable track recording to save your path
+
+### Tips
+
+- Ensure gpsd is running: `sudo gpsd /dev/ttyUSB0 -F /var/run/gpsd.sock`
+- GPS fix may take 30-60 seconds after cold start
+- Accuracy improves with more satellites in view
+
+## TSCM (Counter-Surveillance)
+
+1. **Select Sweep Type** - Choose from Quick Scan (2 min), Standard (5 min), Full Sweep (15 min), or presets for Wireless Cameras, Body-Worn Devices, or GPS Trackers

+
+### Threat Levels
+
+- **Informational (0-2)** - Known or expected devices
+- **Needs Review (3-5)** - Unusual devices requiring assessment
+- **High Interest (6+)** - Multiple indicators warrant investigation
+
+### Tips
+
+- Record a baseline in a known clean environment before conducting sweeps
+- Use the meeting window feature to flag new RF signatures during sensitive periods
+- Full functionality requires WiFi adapter, Bluetooth adapter, and SDR hardware
