Fix module dependency resolution issues

Browse Source 
- Fix dependency resolution to use built modules from /lib/modules/6.12.44-Zero-OS instead of fresh container
- Fix stage1/stage2 configuration mismatch (only using stage1 modules as intended)
- Fix firmware parsing to ignore comments in modules.conf
- Fix variable binding issues for incremental builds (FULL_KERNEL_VERSION, KERNEL_OUTPUT)
- Module resolution now properly expands 31 → 48 modules with dependencies
- Firmware requirements reduced from 157 bogus → 3 correct packages
- All 48/48 resolved modules validated as available .ko files
