Add five action.array.push|set|remove|pop|clear node kinds; replace the
legacy {t,v} in-memory arrays store with array locals as single source of
truth; alias action.accumulate→push and action.clear→array.clear for
backward compat; rewrite action.export as index-aligned CSV with custom
header labels; add ensureArrayDecls() auto-declare migration wired via
Canvas.tsx so undeclared arrays referenced by logic nodes are initialised.
