Telemetry event definitions and emission helpers for x402 operations.
All events emitted by this library use the [:x402, module, operation] format
and include %{count: 1} as measurements.
Emitted events:
[:x402, :payment_required, :encode][:x402, :payment_required, :decode][:x402, :payment_signature, :decode][:x402, :payment_signature, :validate][:x402, :payment_signature, :decode_and_validate][:x402, :payment_response, :encode][:x402, :payment_response, :decode]
Metadata always includes :status (:ok or :error) and may include
additional operation-specific fields such as :reason, :header, or
:fields.
