The first walking-skeleton cycle: the aura-core data substrate everything
streams through — the four scalar base types (Scalar/ScalarKind/Timestamp,
C7), the fixed-capacity financial-indexed SoA Column with its zero-copy
Window (C8), the type-erased AnyColumn edge with an edge-time kind check
(C7), and the per-column run_count freshness primitive (C5). Sharpens the
RustAst reference: no boxed Value, no VecDeque, no RefCell/Rc, no per-event
allocation. Node trait, Ctx, firing policies, and the sim loop are deferred
to subsequent cycles.

Cargo workspace aura-core -> aura-engine -> aura-cli (bin `aura`) plus nodes/ for hot-reloadable cdylib node crates. Crate bodies are intentionally API-free; types arrive from the first spec. Adds the skills profile (.claude/dev-cycle-profile.yml), the project CLAUDE.md with the eight domain invariants, and the design-ledger skeleton.
