feat: add context7-mcp to Crush integration

Build and validate Context7 Documentation MCP Server (v2.1.0).

Changes:
- mcp-context7-wrapper.sh: Created wrapper script with container cleanup
- crush.json: Added context7-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 (224MB, Node.js + TypeScript)
- MCP protocol handshake verified with initialize request
- Protocol version 2024-11-05 confirmed
- Server name: Context7, version 2.1.0
- Wrapper script tested and working
- Environment variables: UPSTASH_REDIS_REST_URL, UPSTASH_REDIS_REST_TOKEN

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

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