fmridesign 0.6.0

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.

contrast_weights() and Fcontrasts() for event_model objects now name interaction-term contrasts with the same term tags used by design-matrix col_indices, preventing downstream consumers from dropping crossed-term contrasts because of :/_ key mismatches (#9).
event_model() now warns when continuous parametric modulators are all-zero or have zero variance, catching degenerate design columns before model fitting while preserving the existing design-matrix shape (#8).
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.
