New Features：
- Optimized the extruder homing sequence by adding a lifting logic before homing. This resolves the issue of the nozzle scraping against the print bed during homing.
- Added a forced left extruder logic for bed leveling before printing. This prevents leveling abnormalities caused by using the right extruder for leveling after completing a right extruder print job.
- Increased the printer’s built-in maximum extruder acceleration to 5000mm/s², for better compatibility with more template settings and to reduce print time for single-extruder print jobs.
