v0.0.22 — Storage & Checkpointing

Added

• Storage & Checkpointing (BYOK + Gateway modes)

  • kit.withStorage({ url: "s3://..." }) for BYOK S3-compatible storage
  • Gateway mode via EVOLVE_API_KEY (Evolve-managed storage)
  • Auto-checkpoint after every successful run()
  • Content-addressed dedup (SHA-256 hash, skip upload on match)
  • Restore via kit.run({ from: checkpointId }) or from: "latest"
  • Explicit save points via kit.checkpoint({ comment })
  • kit.listCheckpoints({ limit, tag }) for checkpoint discovery
  • Standalone listCheckpoints(storageConfig) without Evolve instance
  • Lineage tracking with parentId across runs and restores

• Python SDK parity for all storage/checkpointing features

Fixed

• BYOK restore error differentiation (not-found vs network errors)
• s3ListCheckpoints limit+tag ordering bug
• Path traversal protection in normalizeAgentDir() and normalizeWorkspaceDir()
• Daytona provider reliability and cross-provider test isolation
