feat(anthropic): Gate output collection on data_collection option

[ericapisani]

Output data (text and tool calls) is now gated on the data_collection
configuration, mirroring input collection behavior. When data_collection
is configured, its gen_ai.outputs setting is respected. When not configured,
falls back to the legacy send_default_pii and include_prompts behavior.
