[CLD-1396]: feat(cld/runtime): add support to execute registered changesets from YAML input

[graham-chainlink]

What changed

• Added shared durable pipeline YAML utilities in engine/cld/durablepipeline for parsing, changeset lookup, and payload JSON construction.
• Added ExecRegisteredChangesetsFromYAML to runtime to execute registered changesets in YAML order with per-entry input handling.
• Refactored legacy CLI durable pipeline YAML handling to reuse shared parsing/building logic instead of duplicating implementation details.
• Build a bridge so we can pass input down instead of using env var DURABLE_PIPELINE_INPUT

Why

This centralizes durable pipeline YAML behavior in one path used by both CLI and runtime, reducing drift and making integration tests consume the same execution semantics as production tooling.

Usage example

rt := runtime.NewFromEnvironment(env)
// or rt := New(t.Context(), WithEnvOpts(
//	        	testenv.WithEVMSimulatedN(t, 1)
//	     	))

inputYAML := []byte(`environment: testnet
domain: ccip
changesets:
  - 0001_example_changeset:
      payload:
        foo: bar
`)

err := rt.ExecRegisteredChangesetsFromYAML(func() changeset.RegistryProvider {
	return NewDurablePipelinesRegistryProvider()
}, inputYAML)
if err != nil {
	return err
}

// Examine execution results from the runtime instance.
// rt.State().Outputs
// rt.State().DataStore
// rt.Environment()
