v0.1.4

Pure additive release. The implementation files have shipped in earlier releases under deep paths; this release brings them to the package root so adopters writing receivers, builders, or auditor clients can import everything they need from @adastracomputing/ink directly.

New root-level exports:

• Receipts (./ink/receipts): buildReceipt, shouldSendReceipt, sendReceiptFireAndForget. The canonical INK delivery-receipt builders, signing helpers and fire-and-forget transport. A receiver that wants to ack inbound envelopes per Auditability §6 can drop these in without rolling its own.
• Transport-auth (./ink/transport-auth): resolveEffectiveTransports, checkTransportAllowed. The token-level transport allowlist enforcement, including the "field absent vs empty array" semantics. Required for any extension token issuer.
• Discovery-gating (./ink/discovery-gating): buildRedactedCard, shouldRedactOnGet, AgentCardQuerySchema. Visibility-aware Agent Card responses (public, network_only, capability_gated, private).
• Checkpoint parsing (./ink/checkpoint): parseCheckpoint, formatCheckpoint, CheckpointData. For consumers of transparency-log signed checkpoints.
• Audit event schemas + types (./models/ink-audit): InkAuditEventTypeSchema, InkAuditEventSchema, InkAuditInclusionSchema, InkReceiptSchema, InkAuditQuerySchema, InkIntroductionReceiptSchema, plus matching types InkAuditEventType, InkAuditEvent, InkAuditInclusion, InkReceipt, InkAuditQuery, InkAuditResponse, InkIntroductionReceiptStatus.
• Handshake message schemas (./models/ink-handshake): InkChallengeSchema, InkRejectionSchema, InkResolutionSchema, type AgentCardVisibility.
• Agent Card schema (./models/agent-card): AgentCardSchema (the type was already exported).
• Encryption key encoder (./crypto/keys): encodeEncryptionKeyMultibase (the encoder companion to the already-exported decodeEncryptionKeyMultibase from 0.1.3).

No wire-level changes. No behavior changes inside the existing functions. Receivers on 0.1.3 work unchanged on 0.1.4.

Per the pre-1.0 policy this release publishes under the next dist-tag.
