Add nsbx — the Neuron Sandbox primitive

Browse Source 
Generalise the ad-hoc cog-arch (worktree+build+store-clone+C-tests) and
store-fix (secondary soul + launchctl rails cutover) proto-sandboxes into one
reproducible primitive: run experiments and code changes against the REAL
engram runtime on an isolated snapshot of the live mind, with a gated
promote-to-prod path.

Dev environment as a primitive — any team member gets a private, isolated copy
of the mind (separate port/store/process); prod on :8742/:7770 is untouchable
from a sandbox. Wraps the real binary; never reimplements engram logic.

Lifecycle: create/up (consistent store+WAL+config snapshot; place OR build the
runtime from --source/--branch/--binary; boot on an isolated port) · build ·
run · validate (rails as checks: zero-loss under load+reboot, reboot-prove, RSS
bound, retrieval parity, keystone integrity) · promote (gated rails cutover:
snapshot-first, additive binary swap, bootout→settle-poll→bootstrap, verify,
auto-rollback; never pkill/kickstart -k; dry-run unless approved) · destroy.

Dogfooded: reproduced retrieval-parity 25/25 vs baseline and the cog-arch
correspondence-loop known result (Brier 0.028648->0.000586, reboot-proven) and
real-store reboot-prove at 10994-node scale, all inside a sandbox; prod
untouched.

# cog-arch correspondence-loop dogfood — RUN INSIDE the sandbox via `nsbx run`.
# Compiles the REAL engram C runtime + cognition tests and reproduces the known
# calibration result (memory 194c69c8): held-Brier 0.028648 -> 0.000586, reboot-proven,
# then reboot-proves the Stance persistence against a SCRATCH COPY of THIS sandbox's
# clone of the real store (never live, never the running daemon's file).
