Add comprehensive example BOM with multi-supplier support

Browse Source 
- Add example-project_bom_v1.0.0_2024-08-04.csv with complete STM32F401-based design
- Include all requested fields: Designator, Qty, MPN, Manufacturer, Package, Description, RoHS
- Add comprehensive supplier part numbers for Digi-Key, Mouser, and LCSC
- Include additional technical fields: Value, Tolerance, Voltage/Power Rating, Temperature Range
- Add pricing information and datasheet URLs for complete component traceability
- Cover typical hardware components: MCU, power regulation, connectors, passives, LEDs, test points
- Update hardware/bom/README.md with detailed field descriptions and example reference
- Follow file naming conventions with semantic versioning and YYYY-MM-DD date format
- Provide multi-sourcing flexibility for component procurement and PCB assembly services
