Add simple BC-based FillFIT following ZDC pattern
- Add simple FillFIT(bc) template function in VarManager.h that takes BC object directly - Accesses FIT detectors via bc.has_foundFT0(), bc.foundFT0(), etc. like ZDC does - No initialization overhead, only fills values when detectors are present - Update tableMaker to use simple VarManager::FillFIT(newbc) call - Remove FT0s, FDDs, FV0As table arguments from fullSkimming and skimCollisions - Remove FIT detector subscriptions from processPbPbWithFilterBarrelOnly - FIT information now accessed directly from BC objects, not from separate tables 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
