Pact v1.1.0

What changed

• Added typed readiness profiles so operational maturity, security, privacy, compliance, gating, testing, and monitoring are decided before decomposition.
• Added AI-editable build_spec.yaml support through pact init --spec, pact spec apply, and pact spec show.
• Added optional production-readiness artifact packs through pact production init, pact production status, pact production fingerprint, and pact production validate.
• Updated package metadata, README, docs, and pact.tools links for the new canonical site.

Behavior

• Pact remains plan-first by default. pact run still stops after decomposition, contracts, and tests unless --implement is explicitly supplied.
