swarm: bind reshape's proven primitives — REAL-COGNITION local swarm end-to-end

Binds the api-reshape surface at wt/api-reshape@d4f401d (op_think/read/attend/
learn, verified against engram.cognition-20260814) into the swarm:
- reshape_surface.el composes the reshape's proven read/cognition primitives
  verbatim (write ops omitted — they need the gate-1 write-healthy clone).
- primitive_binding.el: bound_think -> op_think over the worker's NODE-ID
  anchor (ctx.input); attend/learn bound behind SWARM_WRITE_HEALTHY.
- cognize blueprint derives the vote verdict from the REAL gradient's n_support
  (json_get_int) — per-anchor diversity (6/16/87 support) drives a genuine vote.
- build.sh now defines HAVE_CURL. CRITICAL FIX: without it every http_* was a
  '{"error":"not built with HAVE_CURL"}' stub, so prior 'live engram'
  retrieval was a false positive (matched the ref string, not real content).
  With HAVE_CURL the swarm genuinely hits /api/think on the :8901 clone.

harness_real_cognition.el: 17/17 GREEN with seam=decorated — 8 native-thread
workers each a REAL think (768-dim gradient) over its CCR-scoped node-id anchor,
@manager reduce+vote convergence, all 3 containment rules incl. live Rule-2
denial, afferent telemetry (8 real think signals), durable work-tracking. Reads
only — daemon stays healthy; writes stay gated on the gate-1 clone. Prod :8742
untouched.
