Description: Provides tools for event-study analysis and inference in
        difference-in-differences (DiD) designs with panel data, from
        the classic two-way fixed-effects (TWFE) event study to
        estimators for staggered adoption. Includes event_study() for
        event-study curves (dynamic effects by relative time), att()
        for aggregated ATT estimation (overall, by cohort, by calendar
        time), did() for basic two-way fixed-effects DiD, and
        honest_sensitivity() for sensitivity analysis under violations
        of parallel trends (Rambachan and Roth, 2023), all running on
        an internal C++ fixed-effects OLS engine. Supports multiple
        modern estimators: Callaway-Sant'Anna (2021), Sun-Abraham
        (2021), Borusyak-Jaravel-Spiess (2024), Wooldridge TWM, and Deb
        et al. FLEX. Results plot via base plot() methods.
