fix(reliability): engram-connection

- entrypoint.sh: extend engram health-check timeout 30->60s; set
  EL_HTTP_TIMEOUT_MS=10000 and EL_HTTP_CONNECT_TIMEOUT_MS=3000 to bound
  awareness loop blocking window to 10s/call (down from 60s default)
- soul.el: 3-attempt retry loop for boot-time /api/nodes+/api/edges fetch;
  validate non-empty JSON array before loading to prevent silent zero-node
  identity graph from transient post-healthcheck network hiccup
- awareness.el: soft circuit-breaker in ise_post (opens after 3 failures,
  30s backoff, half-open probe); /api/sync refresh skips HTTP call when
  breaker is open; error-JSON detection on sync response

TODOs: full async dispatch, connection pooling (require EL futures/persistent curl)
