feat(runtime): v0.0.25 — AgentIdentity pallet wired runtime composition Index 9

Phase 2.7 AGENT IDENTITY pallet wired canonical en frame_support::runtime macro
como Index 9 (post-Fees Index 8). 9 → 10 pallets composed canonical. Config trait
RuntimeEvent association wired canonical (pattern Provenance + Fees mirror).

## Changes

- crates/origin-chain-runtime/src/lib.rs:298 — Index 9 pub type AgentIdentity = origin_chain_agent_identity::Pallet<Runtime>
- crates/origin-chain-runtime/src/configs.rs:362 — impl origin_chain_agent_identity::Config for Runtime { type RuntimeEvent = RuntimeEvent }
- crates/origin-chain-runtime/Cargo.toml — origin-chain-agent-identity workspace dep + std feature
- crates/origin-chain-node/src/main.rs — 9 → 10 pallets listed + AgentIdentity Index 9 highlighted [Phase 2.7 scaffold v0.0.25]
- crates/origin-chain-agent-identity/src/lib.rs — Config constraint AccountId = origin_chain_types::AccountId REMOVED (usa T::AccountId generic compatible runtime ChainAccountId AccountId32) + storage updated + events updated

## Verification

- cargo build -p origin-chain-runtime 5.26s clean
- cargo test --workspace — 149 tests passing, 0 failures
- cargo build --release -p origin-chain-node 3.96s clean
- origin-chain-node info muestra 10 pallets canonical

🔌 Phase 2.7 wired canonical. Real impl v0.0.26 next.

 ## [Unreleased]
 
+## [0.0.25] — 2026-05-25 — Phase 2.7 wired — AgentIdentity pallet runtime composition Index 9
+
+**🔌 Phase 2.7 AGENT IDENTITY pallet WIRED runtime composition canonical** —
+`origin-chain-agent-identity` añadido al `#[frame_support::runtime]` macro como
+Index 9 (post-Fees Index 8). 9 → **10 pallets** composed canonical. Config trait
+`RuntimeEvent` association wired canonical en `crates/origin-chain-runtime/src/configs.rs`
+(pattern Provenance Phase 2.1 + Fees Phase 2.4 mirror).
+
+### Deliverables v0.0.25
+
+**Runtime composition canonical (Index 9 added)**:
+- `crates/origin-chain-runtime/src/lib.rs:298` — `#[runtime::pallet_index(9)] pub type AgentIdentity = origin_chain_agent_identity::Pallet<Runtime>;`
+- `crates/origin-chain-runtime/src/configs.rs:362` — `impl origin_chain_agent_identity::Config for Runtime { type RuntimeEvent = RuntimeEvent; }`
+
+**Workspace deps canonical**:
+- `crates/origin-chain-runtime/Cargo.toml:51` — `origin-chain-agent-identity.workspace = true` dep + std feature
+- Documentation canonical pattern Provenance + Fees mirror
+
+**Pallet Config canonical fix**:
+- Removed constraint `AccountId = origin_chain_types::AccountId` from `Config` trait — usa generic `T::AccountId` (matches runtime ChainAccountId AccountId32)
+- Storage canonical updated: `Identities<StorageMap<_, _, T::AccountId, AgentIdentity>>` + `DidToAccount<StorageMap<_, _, Did, T::AccountId>>`
+- Events updated: `AgentRegistered/AgentBound/AgentUpdated { account: T::AccountId, ... }`
+
+**Node info subcommand update canonical**:
+- `crates/origin-chain-node/src/main.rs:194` — 9 → **10 pallets** listed canonical
+- Index 9 AgentIdentity highlighted `[Phase 2.7 scaffold v0.0.25]`
+
+### Verification end-to-end canonical
+
+- ✅ `cargo build -p origin-chain-runtime` 5.26s clean (warnings cosméticos macro-generated)
+- ✅ `cargo test --workspace` — **149 tests passing**, 0 failures (+12 nuevos: 8 identity types + 4 pallet scaffold)
+- ✅ `cargo build --release -p origin-chain-node` 3.96s clean
+- ✅ `origin-chain-node info` muestra 10 pallets canonical + 13 Runtime APIs (AgentIdentityApi pendiente v0.0.27)
+- ✅ Existing subcomandos canonical NO regression
+
+### Roadmap canonical post-v0.0.25
+
+| Version | Trigger |
+|---------|---------|
+| **v0.0.26** | **Real `register_agent_did` impl + storage assertions + mock runtime integration tests E2E (sesión 3+ shipping ahora, pattern v0.0.22 mirror)** |
+| v0.0.27 | Runtime API canonical `AgentIdentityApi.query_identity` impl en runtime → **Phase 2.7 COMPLETE** |
