Source changelog

**Introduces outcome contract and tighter delivery standards for paid x402 service execution.** - Added requirement to freeze and reference an explicit "outcome contract" specifying the desired result dimensions before payment or fulfillment. - Workflows now demand a match with the frozen outcome contract before successful delivery; material mismatches (market, count, type, staleness, etc.) are classified as result_mismatch. - Condensed user interaction: internalizes plan/lookup/discovery steps, reduces clarification requests, and restricts chat confirmations between proof creation and use. - Clarified interaction flow and protocol/version handling: freeze the protocol version before payment; do not ask the user to "pay again" for mismatches. - Removed the skill-card.md file.
