AshTypescript.Manifest.Verifiers.VerifyTypedQueryFields (ash_typescript v0.18.0)

Verifies that every typed query's fields selection references valid, public fields on its resource.

Reads typed_queries from the persisted rpc_configs and routes each one through RequestedFieldsProcessor.process/3 — the same machinery that handles field selection at runtime. The result is that compile-time validation and runtime parsing share one source of truth: if the verifier passes, the typed query is callable; if it fails, the field selection is structurally wrong.

Missing or non-public referenced actions are reported by AshTypescript.Manifest.Verifiers.VerifyRpc; we skip them here to avoid duplicating that diagnostic against the same root cause.
