Lab defaults are unchanged; each can now be overridden without editing yaml:
EGOVERSE_DATASET_DIR -> paths.dataset_dir
EGOVERSE_LOG_DIR -> paths.log_dir (default $PROJECT_ROOT/logs, i.e. ./logs)
EGOVERSE_PI05_WEIGHTS -> model/pi0.5_base pytorch_weight_path
WANDB_ENTITY / WANDB_PROJECT -> logger/wandb entity / project

• train_zarr_cartesian: hydra.run.dir and hydra.sweep.dir are
  ${paths.log_dir}//_ instead of a literal ./logs/...
• paths.root_dir default is . (launch dir), not ${hydra:runtime.cwd}: the
  launchers read hydra.sweep.dir -> paths.log_dir -> paths.root_dir before a
  HydraConfig exists, so any ${hydra:...} there breaks every -m launch.
• README: table of the variables.
• tests/unit: test_env_overrides (defaults, overrides, hydra.run.dir, and a
  real hydra.main -m hydra/launcher=basic run in a subprocess, which is the
  only check that exercises the launcher's sweep-dir resolution);
  tests/unit/conftest.py holds the shared compose+resolve helper as a fixture
  that also resets the HydraConfig singleton. test_hydra_configs also resolves
  the hydra.launcher node for every launcher yaml (gres ${eval:} strings,
  signal_delay_s).
