fmridesign 0.6.0

New features

• baseline_model() now checks nuisance_list inputs during construction for zero-variance columns, duplicate or near-duplicate columns, non-finite values, nuisance rank deficiency, and columns aliased with baseline terms.
• Added nuisance_check = c("warn", "error", "drop", "none") to control whether nuisance problems warn, stop, are dropped with an audit warning, or are skipped.
• Added check_nuisance() and clean_nuisance() helpers for inspecting and repairing block-wise nuisance regressors before model construction.

Bug fixes

• Fixed list-based event_model() specifications so hrf(..., subset = ) expressions can use base operators and helper functions from the calling environment, matching formula-interface subset behavior.
• Fixed event-model column metadata construction for factor and multi-basis HRF terms that expand to multiple design columns.
