Z3r0 v0.2.1

Added

• Added host management with SSH terminal access and Docker TLS certificate support for managed hosts.
• Added dynamic sandbox egress proxy management, Tor-only sandbox egress, image-scoped sandbox control ports,
  and proxied noVNC access with container ownership control.
• Added bilingual product documentation and a manual GitHub Pages deployment script.
• Added sandbox artifact triage skills and a quick-open action for sub-agent messages.

Changed

• Reworked the sandbox proxy into a modular Go proxy with shell, files, WebSocket, entry proxy, egress proxy,
  and PTY resize handling.
• Replaced the WorkProject graph renderer with Cytoscape.
• Strengthened coordinator and specialist agent instructions around coverage, retesting, MITRE ATT&CK-aligned
  methodology, and failure-seeking completion review.
• Refined frontend layout, resource styling, playground streaming behavior, sandbox controls, and admin resource
  interactions.

Fixed

• Fixed the default database port mismatch between runtime configuration and Docker Compose.
• Fixed first-message playground streaming so REST-submitted turns render immediately.
• Fixed host password field display, sandbox container hash display, Select prefix icon spacing, and Semi UI
  button usage.
• Hardened git ignore coverage and normalized sandbox skill resource path handling.
