feat(MCH-010): Complete MCP Server with 24 tools

- Add salesTools (4 tools): get_daily_sales, get_sales_report,
  register_sale, get_today_summary
- Update index.ts to include salesTools in allTools array
- Add .gitignore for node_modules and dist

Tools now cover 6 categories:
- products (5), orders (4), fiado (4)
- customers (3), inventory (4), sales (4)
