feat: add ghost-mcp to Crush integration

Build and validate Ghost CMS MCP Server (ghost-mcp-ts v1.0.0).

Changes:
- mcp-ghost-wrapper.sh: Created wrapper script with container cleanup
- crush.json: Added ghost-mcp entry with type: stdio and timeout: 60
- STATUS.md: Updated working MCP list and detailed status table
- JOURNAL.md: Documented integration with full validation results

Validation:
- Container builds successfully (284MB, Node.js + TypeScript)
- MCP protocol handshake verified with initialize request
- Protocol version 2024-11-05 confirmed
- Server name: ghost-mcp-ts, version 1.0.0
- Wrapper script tested and working
- Environment variables: GHOST_API_URL, GHOST_ADMIN_API_KEY
- Capabilities: resources, tools, prompts (all listChanged: true)

This is third MCP added in alphabetical order after filtering
out already working MCPs (audiobook, bitwarden, blender, cloudron,
context7, docker, drawio, elasticsearch, freecad).

Following ADR-007: Sequential Server Validation - one MCP at a time,
awaiting user validation before proceeding to next MCP.
