Johnathan Corgan a50473fe9f Improve Docker mesh setup: data-driven topologies, identity derivation, services ...

Config system overhaul:
- Add mesh-public topology (5 Docker nodes + external pub node at 217.77.8.91)
- Refactor generate-configs.sh to read topology YAML files directly,
  replacing hardcoded lookup functions, with multi-char node ID support
- Generate npubs.env with all node npubs; sourced by test scripts and
  injected into containers via docker-compose env_file directive
- Add .env with COMPOSE_PROFILES=mesh so docker compose defaults to
  mesh topology without requiring --profile

Deterministic mesh identity derivation:
- Add derive-keys.py: pure Python tool (no deps) deriving nsec/npub
  from sha256(mesh-name|node-id) via secp256k1 and BIP-173 bech32
- generate-configs.sh and build.sh accept optional mesh-name argument;
  Docker node identities are derived while external nodes keep
  hardcoded keys from topology YAML

Docker compose improvements:
- Add mesh-public profile service definitions
- build.sh now runs docker compose build automatically, providing a
  single command for the full binary+configs+images pipeline
- Ping test script supports mesh-public topology

Container services:
- Add HTTP server on port 8000 (IPv6-bound) serving static page,
  accessible over FIPS overlay via npub.fips hostnames
- Add rsync to container packages

Documentation:
- Comprehensive README update covering topology system, identity
  derivation, npubs.env, and container background services (SSH,
  iperf3, HTTP) with usage examples
