feat(revive): v0.0.37 — pallet-revive workspace scaffold + ChainAction Phase 3 extension 🎉

Phase 3 Slice 3.1 Ship 1 SCAFFOLD shipped. Path A inicio post sesión 3+
extended histórica (35 ships v0.0.1→v0.0.36 + Slice 2e WASM RESUELTO). David
autorizó "vamos con todas en orden desde A" — pallet-revive smart contracts
PolkaVM RISC-V + ink! v6 + Solidity per SBS-5 ratificado (supersedes CHN-6 v1.0).

Cambios:
- Cargo.toml workspace.dependencies: pallet-revive 0.12.2 + pallet-revive-uapi 0.13.0
  Version pin canonical para stable2512-3 verificado vía
  github.com/paritytech/polkadot-sdk/blob/polkadot-stable2512-3/substrate/frame/revive/Cargo.toml
  (latest 0.17.0 requiere bump Substrate generation — scope Phase 8+).
- crates/origin-chain-types/src/actions.rs: ChainAction enum extension OCAFB-2
  semver-respecting con 3 nuevas variants ordinals 4/5/6:
  * DeployContract (pallet-revive::instantiate)
  * CallContract (pallet-revive::call)
  * UploadContractCode (pallet-revive::upload_code sin instantiate)
  Ordinals 0-3 {Read/Write/Compute/Transfer} preservados intactos. Wire format
  stable canonical — name() snake_case + ordinal() u8 + from_ordinal() forward-compat
  + serde + scale-codec roundtrip todos actualizados. +1 test
  chain_action_phase_3_variants_distinct_from_legacy.
- crates/origin-chain-fees/src/fee_schedule.rs: subsidy_basis_points + entitlement_unlocked
  matches updated exhaustivamente para 3 nuevas variants. Mapping interim conservador
  (DeployContract/UploadContractCode ~= Write semantics, CallContract ~= Compute).
  Refinement Phase 3.2 con Mathi OitFeeSchedule extension post-OCAFB ratify +
  measurements empíricos gas/deposit reales.

Verificación:
- cargo check --workspace clean (0 errors, warnings pre-existentes)
- cargo test --workspace: 203 tests verde (baseline 202 + 1 new test) 0 failures
- ChainAction actions::tests 7/7 verde (4 originales updated + 3 nuevos covered)

Próximo Ship 2 v0.0.38: pallet-revive wired runtime Index 11 (27 Config types
associated types + parameter_types canonical Asset Hub Westend reference).

⚓ Path A Phase 3 kickoff. La nave continúa zarpando.
