agent: typed parser for bbot JSONL output (F10b)

Parse bbot output.json reading only the typed fields (type,
scope_distance, host, url, port, module, module_sequence), validated.
The free text (data, or data_json with the FINDING description) is kept
only as one Go-quoted inert string, never used for scope or an action.
Unknown keys are ignored. Events at scope_distance 0 are the only ones
mapped to insert_assets items, from their typed host; any other distance
becomes a third_party_intel item that is never auto-scoped.
