✅ Review Round 13: Fix NetCDF write and directory branding

CMIP7 naming now fully functional!

Changes:
1. Fixed directory branding_suffix lookup (prioritize rule config)
2. Added NetCDF4 compression constants (NETCDF_COMPRESSION_LEVEL=4)
3. Temporarily exclude lat_bnds/lon_bnds to avoid NetCDF write error
   - Large unstructured grids (3M+ cells × 16 vertices) cause issues
   - Workaround: Skip boundary variables until NetCDF4 fix available
   - Coordinates (lat, lon) still included correctly
4. Updated .gitignore to exclude logs, cache, and output files

Results:
✅ Filename: tos_tavg-u-hxy-sea_mon_glb_gn_AWI-ESM3-VEG-LR_piControl_r1i1p1f1_135001-135012.nc
✅ Directory: MIP-DRS7/CMIP7/CMIP/AWI/.../glb/mon/tos/tavg-u-hxy-sea/gn/v*/
✅ Compression: zlib level 4 with shuffle
✅ File size: ~49 MB gn (was 937 MB), ~22 MB gr
✅ Data written: time=12 timesteps

Note: Boundary variables excluded as temporary workaround for NetCDF write bug
with large multi-dimensional arrays on unstructured grids.
