rd2d 0.1.0

• Adds fuzzy boundary RD support for both location-based and distance-based methods, including fuzzy main effects, ITT, first-stage, and optional one-sided outputs.
• Adds params.other and params.cov controls to rd2d() for optional companion tables and covariance storage.
• Moves location-based uniform confidence band, WBATE, and LBATE construction to summary.rd2d().
• Adds distance-based WBATE and LBATE construction to summary.rd2d.distance(), including fuzzy main, ITT, and first-stage outputs.
• Updates location-based return tables to use lowercase column names such as estimate.p, std.err.q, t.value, and p.value.
• Fixes location-based covariance construction for signed cross-evaluation covariance, clustered finite-sample scaling, and right-sided simulated critical values.
• Fixes distance-based covariance construction to use signed local-polynomial residuals, corrected cluster covariance halves, and side-specific bandwidth plug-in matrices.
• Adds CER-optimal bandwidth selectors cerrd, certwo, icerrd, and icertwo for location-based and distance-based methods.
• Replaces the distance-based kink/rbc options with kink.unknown and kink.position, including adaptive known-kink bandwidths based on boundary point locations.
• Uses smooth-boundary robust bias-corrected inference as the distance-based default, and uses the same stabilized Gram-matrix inversion helper as the location-based methods.
• Uses q = p by default for distance-based unknown-kink specifications to avoid compounding the unknown-kink bandwidth shrinkage with an additional polynomial-order change.
• Aligns distance-based return tables with location-based naming conventions, including main, main.0, main.1, bw, estimate.p, std.err.q, N.Co, and N.Tr.
• Updates public notation to use fuzzy for treatment receipt/status, tau.itt/tau.itt.q for reduced-form outcome estimates, tau.fs/tau.fs.q for first-stage estimates, assignment for assignment, cluster for cluster identifiers, and distance for signed distance scores.
• Removes user-facing derivative notation from distance-based help files and printed output.
• Adds focused tests for location-based returns, lazy confidence bands, aggregate inference, covariance regularization, clustered covariance consistency, and numerical preservation.
• Adds focused tests for distance-based return names, fuzzy outputs, heteroskedastic and clustered standard errors, covariance diagonals, aggregate inference, and polynomial-order validation.
• Simplifies repository illustration files to R/rd2d_illustration.R and R/rd2d_plot.R.
