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)

-// LLM reliability — issues that require C runtime fixes (el_runtime.c).
-// These cannot be addressed at the EL layer; they are documented here so the
-// symptoms are traceable back to their root causes.
-//
-// Issue #1 (no retry on timeout/connection error):
-//   http_do() in el_runtime.c calls curl_easy_perform() once. On
-//   CURLE_OPERATION_TIMEDOUT / CURLE_COULDNT_CONNECT / CURLE_RECV_ERROR it
-//   returns http_error_json() with no retry. Fix: add a retry loop (max 3
-//   attempts, exponential back-off starting at 1s) inside llm_provider_request().
-//
-// Issue #2 (60s timeout applies to all HTTP calls including LLM):
-//   EL_HTTP_TIMEOUT_MS defaults to 60000ms for every http_do() call.
-//   Fix: introduce EL_LLM_TIMEOUT_MS (default 120000) used only by
-//   llm_provider_request(); leave EL_HTTP_TIMEOUT_MS (default 30000) for
-//   general service calls to avoid holding connections for 60s.
-//
-// Issue #3 (HTTP 429 causes silent provider failover, not backoff):
-//   llm_chain_call() advances to the next provider on any JSON-prefixed response
-//   including 429. Fix: parse HTTP status via curl_easy_getinfo; on 429 sleep
-//   Retry-After seconds (default 5s) then retry the same provider up to 3 times.
-//
-// Issue #4 (HTTP 500/502 crashes the request silently):
-//   Same path as #3 — 5xx responses cause immediate provider failover with no
-//   retry. Fix: retry with exponential back-off (1s, 2s, 4s) before advancing.
-//
-// Issue #6 (no secondary LLM fallback in production):
-//   Set NEURON_LLM_1_URL/KEY/FORMAT in ExternalSecret to a secondary provider
-//   (e.g. Gemini). No C code change required; llm_chain_call() already iterates.
-//
-// Issue #8 (LLM response size unbounded — memory-only cap):
-//   HttpBuf grows via realloc() with no hard limit. Fix: add
-//   EL_HTTP_MAX_RESPONSE_BYTES (default 10MiB) cap in httpbuf_append() and
-//   return http_error_json("response too large") on overflow.
