fix(agent): align World Packet with reviewer feedback and voice parity

Reuse one context/contacts/tracking owner in voice and World Packet. Compare voice outputs after stripping presentation fields; remove the unconsumed fingerprint API pending an actual caller. Document the exported packet boundary and reject null options safely.

Review guidance: asturksever on origin #880; Windows parity diagnosis by quanticsoul4772. Existing source ownership retained.

 The voice card nested in the mic control (`voiceCard.js`) shows captions, plan
 steps and the result. `resultDisplay.js` is the one adapter from a result to
 the card: builder results show as built, and analyst results show a title
