feat(provenance): Phase 2.1 COMPLETE v0.0.17 — Runtime API verify_provenance PROV-8 (8/8 sub-decisions)

🎉 Phase 2.1 PROVENANCE pallet COMPLETE end-to-end canonical 8/8 PROV.

PROV-8 Runtime API verify_provenance wired canonical:
- pallet sp_api::decl_runtime_apis! ProvenanceApi trait declaration
- runtime impl_runtime_apis! impl ProvenanceApi<Block> for Runtime
  delegates a Provenance::attestation_of(hash) storage getter
- 12 Runtime APIs canonical total (anterior 11 + ProvenanceApi nuevo)
- Read-only RPC query canonical sin tx fee canonical
- Node info subcommand updated canonical 12 APIs

Phase 2.1 PROV sub-decisions COMPLETE canonical 8/8:
- PROV-1 Schema separation Noesis/chain ✅
- PROV-2 StorageMap<AssetHash, AssetAttestation> ✅
- PROV-3 Dispatchable attest_asset full flow ✅
- PROV-4 Real Ed25519 verification ✅
- PROV-5 OIT Level >= 3 enforce ✅
- PROV-6 is_anchorable check ✅
- PROV-7 Events emission ✅
- PROV-8 Runtime API verify_provenance ✅ NUEVO v0.0.17

Verification end-to-end:
- cargo check workspace verde 1.84s
- 85+ tests pass workspace (47 types + 6 provenance + 16 runtime + 10 chain_spec + others)
- cargo build release 5.88s clean
- info subcommand muestra 8 pallets + 12 Runtime APIs
- build-spec NO regression Slice 3 mock-WASM chain_spec builder

Honest disclosure: PROV-1..8 complete canonical PERO real chain runtime canonical
aún NO funciona end-to-end por WASM_BUILD_STD/serde leak (Slice 2c+2d findings).
Pallet + Runtime API canonical structurally ready — cuando Slice 2e land, pallet
correrá en real chain runtime canonical.

Cross-pillar consumers desbloqueados canonical: Trinity + Codex + origindocs +
Ethos + Atelier — todos pueden importar ProvenanceApi trait + plan integración.

+**🎉 Phase 2.1 PROVENANCE pallet COMPLETE end-to-end** — 8/8 PROV sub-decisions
+implementadas canonical. PROV-8 Runtime API `verify_provenance` ahora wired
+canonical via `sp_api::decl_runtime_apis!` + impl en runtime `impl_runtime_apis!`
+macro. 12 Runtime APIs canonical total (anterior 11 + nuevo `ProvenanceApi`).
+
+### Deliverables v0.0.17
+
+**Runtime API declaration canonical (pallet crate)**:
+- `crates/origin-chain-provenance/src/lib.rs` — `sp_api::decl_runtime_apis!`
+- `pub trait ProvenanceApi { fn verify_provenance(hash: AssetHash) -> Option<AssetAttestation>; }`
+- Doc canonical extensivo cross-pillar consumers (Trinity, Codex, origindocs, Ethos, Atelier)
+- Phase 2.3 future expansion canonical noted (verify_by_creator, list_in_block, cross_runtime_proof)
+- `sp-api` dep added a pallet Cargo.toml + features std
+
+**Runtime API impl canonical (runtime crate)**:
+- `crates/origin-chain-runtime/src/lib.rs` — `impl origin_chain_provenance::ProvenanceApi<Block> for Runtime`
+- Delegates canonical a `Provenance::attestation_of(hash)` storage getter
+- Read-only canonical sin tx fee (off-chain RPC query)
+
+**Node info subcommand update**:
+- `crates/origin-chain-node/src/main.rs` — 11 → 12 APIs listed

+PROV-1..8 complete canonical PERO real chain runtime canonical aún NO funciona
+end-to-end por canonical el WASM_BUILD_STD/serde leak structural (Slice 2c+2d
+findings documented). El pallet + Runtime API canonical son compilable + tests
+verde + structurally ready. Cuando Slice 2e land (resolve serde/std leak +
+real WASM_BINARY canonical), pallet correrá en real chain runtime canonical.
+
+Mientras tanto: Slice 3 mock-WASM chain_spec builder sigue operativo. Cross-pillar
+consumers pueden lo siguiente canonical:
+- Importar `ProvenanceApi` trait + plan integración pre-mainnet
+- Validar canonical signature flow contra mock attestations (test suite real Ed25519)
+- Design canonical UI components que consumirán `verify_provenance` cuando chain live
+
+### Roadmap canonical post-v0.0.17

+| v0.0.19 | Swap canonical SCALE → postcard encoding cuando Ergon arkhe-noesis-attestation-types Cap 42+ ship (2026-05-30 → 06-05) |
+| v0.0.20 | Phase 2.4 pallet-origin-fees scaffold (paralelo Phase 2.1 pattern) — consumer Mathi HardwareTier via DC OCAFB |
