New features

• Pipe-friendly API: lfq_fit(), lfq_advantage(), lfq_forecast(), lfq_score() enable tidyverse-style chaining with |>.
• Engine registry: register_engine() / unregister_engine() allow third-party packages to register custom modeling engines, similar to the parsnip engine system.
• lfq_summary(): One-row-per-lineage overview combining growth rates, confidence intervals, and relative Rt in a single tibble.
• as.data.frame.lfq_data(): Clean tibble export for interoperability.

Improvements

• fit_model() now accepts both built-in and registered engine names.
• lfq_engines() lists all available engines including custom registrations.
• 251 unit tests (up from 243 in v0.1.0).
