feat: add Mistral Vibe support to mxcli init

Add vibe as a supported tool in mxcli init. Generates:
- .vibe/config.toml with system prompt reference and tool permissions
- .vibe/prompts/mendix-mdl.md system prompt with project context
- .vibe/skills/ with four SKILL.md files: write-microflows,
  create-page, check-syntax, explore-project

Usage: mxcli init --tool vibe

+
+- The mxcli tool is in the project root. Always use ./mxcli, not mxcli.
+- Read AGENTS.md for full project documentation.
+- Read .ai-context/skills/ for MDL syntax patterns before writing scripts.
+- Always validate MDL scripts: ./mxcli check script.mdl -p %s --references
+- Microflow variables start with $. Entity declarations have no AS keyword.
+- Page widgets nest with curly braces { }. Properties use (Key: value).
+- Single quotes in expressions are escaped by doubling: 'it''s here'
+
+## Quick Commands
+
+- Explore: ./mxcli -p %s -c "SHOW STRUCTURE"
+- Check: ./mxcli check script.mdl -p %s --references
+- Execute: ./mxcli exec script.mdl -p %s
+- Search: ./mxcli search -p %s "keyword"
