feat(runtime): v0.0.29 — Governance pallet wired runtime composition Index 10

Phase 5.1 GOVERNANCE pallet wired canonical en frame_support::runtime macro como
Index 10 (post-AgentIdentity Index 9). 10 → 11 pallets composed canonical. Config
trait RuntimeEvent association wired canonical (pattern Provenance + Fees +
AgentIdentity mirror).

## Changes

- crates/origin-chain-runtime/src/lib.rs:315 — Index 10 pub type Governance = origin_chain_governance::Pallet<Runtime>
- crates/origin-chain-runtime/src/configs.rs:382 — impl origin_chain_governance::Config for Runtime
- crates/origin-chain-runtime/Cargo.toml — origin-chain-governance workspace dep + std feature
- Cargo.toml — origin-chain-governance workspace dep default-features = false (no_std-compat)
- crates/origin-chain-node/src/main.rs — 10 → 11 pallets listed + Governance Index 10 highlighted

## Verification

- cargo build -p origin-chain-runtime 15.69s clean
- cargo test --workspace — 165 tests passing, 0 failures
- origin-chain-node info muestra 11 pallets canonical

🔌 Phase 5.1 wired canonical. Real impl v0.0.30 next.
