Release 0.4.0

This release makes the optional MCP server significantly more useful for inspecting and preparing publications without steering agents toward immediate publishing.

Added

• Seven new MCP tools for read operations and safe publishing: get_status, list_publications, list_drafts, get_draft, schedule_draft, unschedule_draft, and publish_draft_checked.
• Pre-publish validation, interactive confirmation requirements, and no-email defaults for the new publish_draft_checked MCP tool.
• Verified MCP client configuration examples in docs/mcp.md.
• Documentation for Gemini CLI with Vertex AI (docs/gemini-vertex-ai.md).

Improved

• Simplify MCP draft creation by routing through the existing Api.create_draft_from_markdown SDK helper, preserving response format.
• Document the legacy publish_draft MCP tool as the compatibility interface.
• Bump cryptography dependency from 48.0.1 to 50.0.0 (#68).
