d37ec1dea5 feat: v1.2.0-alpha — E2E encrypted mesh relay, steganography, relay status polling
Phase 5 mesh networking:
- E2E encrypted TX relay (X25519 + ChaCha20-Poly1305) — non-Archy nodes
  relay encrypted blobs transparently via Meshcore native routing
- Steganographic encoding modes (WeatherStation, SensorNetwork) — traffic
  looks like sensor data on the wire, 0xAA marker, configurable per-node
- Pre-flight Bitcoin Core health check on relay node — specific error codes
  (bitcoin_unreachable, bitcoin_syncing, tx_rejected) instead of generic fails
- mesh.relay-status RPC endpoint — frontend polls for relay result every 3s
- On-Chain / Lightning tabs in Off-Grid Bitcoin panel
- Archy Peers vs Mesh Broadcast relay mode selector
- Mesh view fills viewport (no page scroll), internal panel scrolling
- Version bump to 1.2.0-alpha

Also includes: deploy hardening, container fixes, IndeedHub updates,
boot screen, dashboard improvements, MASTER_PLAN task tracking

e05bb3cc85 feat: Phase 3 Week 2 — Double Ratchet protocol for forward-secret mesh messaging
- Create mesh/ratchet.rs: full Signal-style Double Ratchet implementation
  - DH ratchet with X25519 ephemeral keypairs per step
  - Symmetric-key ratchet via HKDF-SHA256 chain derivation
  - Per-message ChaCha20-Poly1305 encryption with derived message keys
  - Out-of-order delivery via skipped message key cache (max 100)
  - Forward secrecy: old keys zeroized on ratchet step
  - Wire format: 40B header + nonce + ciphertext + tag
- Tests: full conversation, out-of-order, forward secrecy, wire format,
  long conversation (50 messages alternating), message roundtrip
