v1.0.21

Highlights

• Added ZCode as a supported AI harness for Ark model-provider setup, default model selection, and MCP server configuration.
• ZCode setup and reset manage only ArkCLI-owned provider and MCP entries, preserving unrelated user configuration.

Distribution

• Published @volcengine/ark-cli@1.0.21 with binaries for the six supported desktop and server targets.
• Hardened Volc GitHub fallback aftercare so existing dsh-plugins/ content is preserved while version-anchored Skills, README content, and release assets are refreshed.
• Added full desired-tree dry-run validation, top-level path and symlink checks, immutable release-reference validation, and branch-race detection before public writes.

Compatibility

• No breaking CLI flag, structured-output, wire-schema, or public-command changes.
• ZCode web search is MCP-only; ArkCLI does not install a separate web-search Skill for ZCode.
• GitHub remains a fallback; the Volcengine CDN remains the primary binary and Skills source.
