paybond-kit 0.11.4

Release paybond-kit 0.11.4 — fixes policy-file sandbox smoke failing with gateway validation_error when both completion_preset and evidence_schema were sent.

Highlights

• Policy bootstrap fix — policy_sandbox_bootstrap omits evidence_schema when a tool's evidence_preset is set. Gateway sandbox bootstrap rejects both fields together; paybond agent sandbox smoke --policy-file paybond.policy.yaml now binds successfully.
• Guardrails client hardening — bootstrap_sandbox skips evidence_schema in the HTTP payload whenever completion_preset is present.
• Starter templates — bundled templates bumped to paybond-kit>=0.11.4.

Install
