feat: Phase 3 — wire panel modules (heatmap, agent-board, dual-brain, LoRA, sovereignty, earth)

- core/theme.js: export NEXUS with full NEXUS.theme.* properties used by all 6 panels
- core/ticker.js: add subscribe() convenience export so panels can self-register
- data/gitea.js: also write state.agentStatus, activeAgentCount, zoneIntensity, commits, commitHashes
- data/loaders.js: also write state.sovereignty
- data/bitcoin.js: also write state.blockHeight, lastBlockHeight, newBlockDetected, starPulseIntensity
- data/weather.js: also write state.weather
- app.js: import + init all 6 panel modules, bootstrap data polling, call globalTicker.tick()

Fixes #412
Refs #409
