Pausa: 11 crates del fractal Ente #0 con cerebro completo

PID 1 boot + bus interno autenticado + cerebro KCL/Rust:
- 6 lib crates de infra (card, bus, cas, kernel, soma, wasm, snapshot)
- ente-brain: motor de reglas O(1), observer Shannon, cristalización,
  audit hash-chain, persistencia rules.k, Prometheus /metrics
- KCL schemas card.k + rule.k como gramática autoritativa
- compat-logind D-Bus, ente-echo demo provider, ente-zero PID 1
- 22 tests OK, ~3.8k LOC Rust + ~300 LOC KCL
