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.

 ## [Unreleased]
 
+## [0.0.2] — 2026-05-20 — Phase 1.1 "Runtime scaffolding"
+
+Charon sesión 1 continuación. Phase 0.4 → Phase 1.1.
+
+### Added
+
+- `origin-chain-runtime` crate scaffolding (Phase 1.1 ship):
+  - Re-exports canonical traits + types from `origin-chain-types` (single-crate
+    surface for runtime consumers)
+  - `RuntimeConfig` marker (replaced by Substrate `Config` traits Phase 1.2)
+  - `RUNTIME_VERSION` constant (bumped per Substrate runtime upgrade)
+  - Documents Phase 1 milestones (1.1 → 1.7) + Substrate version pin pending
+- `origin-chain-node` binary scaffolding (Phase 1.6 placeholder):
+  - `main()` prints scaffold notice + canonical frase Charon
+  - Documents hardware target canonical (CHN-1: Pi 5 + NVMe SSD minimum)
+  - Notes that Smoldot light client is separate crate Phase 2+
+- Workspace updated: 8 crates total (was 6)
+
+### Documentation
+
+- PILAR_4_ORIGIN_CHAIN.md §6.4 refactored in monorepo (commit `58b88ae`):
+  ink!+origin-mdk reconciliation canonical per CHN-6 + Ergon Cap 36 ratify.
+  Path A discharge by Charon as Pilar 4 domain authority.
+
+### Notes
+
+- Still no Substrate dependencies in this workspace. Phase 1.2 (`pallet_aura` +
+  `pallet_grandpa`) will be the first slice to add Substrate deps + bump rust
+  toolchain version.
+- Future v0.0.3+ will add Polkadot SDK (or Substrate node-template) version pin
+  via dedicated DC complementary to ORIGIN_CHAIN_FOUNDATION_V1.
+
