feat(workspace): Phase 1.1 — runtime + node scaffolding v0.0.2

Charon sesión 1 continuación. Phase 0.4 → Phase 1.1 ship canonical.

## origin-chain-runtime crate (Phase 1.1)
- Re-exports canonical traits + types desde origin-chain-types (single-crate
  surface para runtime consumers)
- RuntimeConfig marker (será reemplazado por Substrate Config traits Phase 1.2)
- RUNTIME_VERSION = 1 constante (bump per Substrate upgrade)
- Docs Phase 1 milestones (1.1 → 1.7) + Substrate version pin pending DC

## origin-chain-node binary (Phase 1.6 placeholder)
- main() prints scaffold notice + canonical frase Charon
- Hardware target documented: Pi 5 + NVMe SSD minimum (CHN-1)
- Smoldot light client noted as separate Phase 2+ crate

## Workspace
- 8 crates total (was 6): added origin-chain-runtime + origin-chain-node
- 44 tests passing workspace-wide
- Build release clean
- cargo run --bin origin-chain-node verified working

## Notes
- Aún sin deps Substrate. Phase 1.2 (pallet_aura + pallet_grandpa) será el
  primer slice que pulls Substrate framework + bumps rust toolchain.
- Polkadot SDK version pin canónica vendrá vía DC complementaria a
  ORIGIN_CHAIN_FOUNDATION_V1 cuando Phase 1.2 inicie.

+//! # origin-chain-runtime
+//!
+//! Origin Chain Substrate runtime composition: FRAME pallets + consensus +
+//! tokenomics + provenance integration. **Scaffold v0.0.2** — Substrate deps
+//! land Phase 1.2 onwards (Charon roadmap).
+//!
+//! ## Phase 1 milestones (Sesiones 4-8)
+//!
+//! - **1.1** `origin-chain-runtime` crate scaffolding  ← **THIS**
+//! - **1.2** `pallet_aura` + `pallet_grandpa` integration (consensus PoA)
+//! - **1.3** `pallet_balances` con OGC token (1B supply genesis)
+//! - **1.4** `pallet_session` (validator rotation, epoch 4h)
+//! - **1.5** `pallet_identity` (Ed25519 DID, wallet creation free)
+//! - **1.6** `origin-chain-node` binary (dev mode, single validator)
+//! - **1.7** Genesis config: allocation 40/25/15/15/5 per BM V2 (CHN-2)
+//!
+//! ## Substrate version pin canonical (Phase 1.2 ratification)
+//!
+//! Charon pin canonical version Substrate cuando Phase 1.2 inicie. Candidatos
+//! actuales:
+//! - **Polkadot SDK 1.x** (frame v4): mainstream, AGI Coretime ready
+//! - **Substrate node-template**: starting point canonical
+//!
+//! Decision se formaliza vía DC complementaria al ORIGIN_CHAIN_FOUNDATION_V1
+//! cuando llegue Phase 1.2. Por ahora `origin-chain-runtime` solo re-exporta
+//! traits + stubs canonical.
+//!
+//! ## Re-exports canonical (Day 1 surface)
+//!
+//! Esta crate re-exporta los traits canonical que el runtime futuro implementa:
+//! `ProvenanceLedger`, `OgcLedger`, `ChainBridge`, `GovernanceProposal`,
+//! `FeeCalculator`. Consumers pueden depender SOLO de `origin-chain-runtime`
+//! para acceder al surface canonical completo.
