zeitR 0.1.0

Full actigraphy pipeline validated epoch-for-epoch (0 / 76,196 mismatches) against the Condor circadiaBase Python reference on an ActTrust recording: detect_offwrist_bimodal(), detect_sleep_crespo(), detect_naps_crespo() (faithful nap_wrapper port), compute_waso().
run_pipeline() gains a params argument (default acttrust_params()); device-specific defaults are now consolidated in one place and can be overridden without touching individual detector calls. wake_thresh is removed from the run_pipeline() signature — it now lives in params$waso$wake_thresh.
run_pipeline() gains a quiet argument to suppress the timestamp-issue warning (useful in batch and testing contexts).

acttrust_params() — exported device parameter preset consolidating all ActTrust-specific defaults across off-wrist, sleep, nap, and WASO stages. Copy and modify to adapt the pipeline to other devices.
label_states() — converts the integer state column to a human-readable ordered factor ("wake", "sleep", "nap", "off-wrist").

End-to-end pipeline parity regression test (test-pipeline-parity.R): epoch-level state, per-layer counts, and nightly statistics locked against python_output.csv and python_nights.csv.
CSPD refiner parity tests (test-cspd-refiner-parity.R): stage-1 peak-valley length filter, stage-2 sleep-gap separation, full .cspd_refine_periods output, and bedtime/getuptime indices against Python intermediates.
Sleep Crespo wiring test (test-sleep-crespo-wiring.R): isolates detect_sleep_crespo(refine = TRUE) against cspd_refined_output.csv.
WASO parity tests (test-waso-parity.R): .nights_df boundaries, per-night statistics, and within-night epoch agreement on boundary-matched nights.

Full package scaffold: read_acttrust(), read_actigraphy(), read_actigraphy_dir(), prepare_actigraphy(), check_consistency(), score_epochs_cole_kripke(), compute_npcra(), study_summary(), run_pipeline_batch().
