Johnathan Corgan 77ac8c822e Add fipstop TUI monitoring tool with smoothed metrics and quality indices
fipstop: ratatui-based TUI for real-time monitoring of a running FIPS daemon.

Tabs and navigation:
- 8 navigable tabs: Node, Peers, Transports, Sessions, Tree, Filters,
  Performance, Routing
- Tab/BackTab navigation with group separators in tab bar
- Table views with selectable rows, detail drill-down panels, and scrollbars

Node tab:
- Runtime info: pid, exe path, uptime, control socket path, TUN adapter name
- Identity: npub, node_addr, ipv6 address
- State summary with peer/session/link/transport/connection counts
- TUN IPv6 traffic and forwarded transit traffic counters

Peers tab:
- Table with Name, Address, Conn, Depth, SRTT, Loss, LQI, Pkts Tx/Rx
- Detail panel: identity, connection info, transport cross-reference,
  tree/bloom state, link stats, MMP metrics with LQI

Sessions tab:
- Table with Name, Remote Addr, State, Role, SRTT, Loss, SQI, Path MTU,
  Last Activity
- Detail panel: identity, session info, traffic stats, MMP metrics with SQI

Transports tab:
- Hierarchical tree view: expandable transport parents with nested links
  (▼/▶ indicators, ├─/└─ tree chars, Space/Arrow to expand/collapse)
- Transport detail: type-specific stats (UDP/TCP/Ethernet)
- Link detail: peer cross-reference with MMP metrics and LQI

Performance tab:
- Link-layer MMP: SRTT, loss, ETX, LQI, goodput per peer
- Session-layer MMP: SRTT, loss, ETX, SQI, path MTU per session
- Trend indicators (rising/falling/stable) with context-aware coloring

Routing tab:
- Routing state: cache sizes, pending lookups, recent requests
- Coordinate cache: entries, fill ratio, TTL, expiry, avg age
- Statistics: forwarding, discovery request/response, error signal counters

Tree tab:
- Spanning tree position with 16 announce stats (inbound/outbound/cumulative)

Filters tab:
- Bloom filter announce stats, per-peer fill ratio and estimated node count

MMP metrics enhancements:
- Add etx_trend DualEwma for smoothed ETX tracking
- Add smoothed_loss() and smoothed_etx() accessors (long-term EWMA)
- LQI (Link Quality Index) = smoothed_etx * (1 + srtt_ms / 100)
- SQI (Session Quality Index) = same formula for session layer
- All loss/ETX displays prefer smoothed values with raw fallback

Control socket:
- Add smoothed_loss, smoothed_etx, lqi/sqi to show_peers, show_sessions,
  and show_mmp JSON responses
- Rename fips_address to ipv6_addr in show_status and show_peers
- Add tun_name and control_socket to show_status
- FHS-compliant 3-tier default path: $XDG_RUNTIME_DIR, /run/fips, /tmp

Node extensions:
- Add started_at/uptime() to Node
- Add tun_name() accessor

Docker sidecar updates:
- TCP transport support via FIPS_PEER_TRANSPORT env var
- Build scripts include fipstop binary

Johnathan Corgan 9668807ca4 Add Docker sidecar deployment for FIPS
Tailscale-style sidecar pattern: a FIPS container provides mesh
networking, and a companion app container shares its network namespace
via network_mode: service:fips.

Security model:
- iptables enforces strict isolation — the app container can only
  communicate over the FIPS mesh (fd::/8 via fips0)
- No IPv4 access: eth0 restricted to FIPS UDP transport (port 2121)
- No IPv6 on eth0: ip6tables blocks all eth0 IPv6 traffic
- Only fips0 and loopback are reachable from the app container

The sidecar accepts peer configuration via environment variables
(FIPS_NSEC, FIPS_PEER_NPUB, FIPS_PEER_ADDR), so it can be pointed
at any FIPS node without config file generation.

Files:
- testing/sidecar/: Dockerfile, Dockerfile.app, docker-compose.yml,
  entrypoint.sh, .env, resolv.conf, scripts/build.sh
- testing/sidecar/README.md: security model, quick-start, architecture,
  DNS resolution, troubleshooting, production considerations
- testing/sidecar/scripts/test-sidecar.sh: 3-node chain integration
  test verifying link establishment, multi-hop connectivity, and
  network isolation on each app container
- .github/workflows/ci.yml: sidecar integration test matrix entry
