Changes in version 0.1.1 (2026-04-05)                  

  - Fix test failure on M1 Mac (ARM64): Wilson CI is not centred on the
    point estimate by construction. Added floating-point tolerance to
    the CI-containment test (test-03-prevalence.R:63). Only the test was
    affected; no changes to estimation code.

                 Changes in version 0.1.0 (2026-04-02)                  

  - Initial release.
  - Core functions: surv_design(), surv_optimize_allocation(),
    surv_lineage_prevalence(), surv_estimate_delay(),
    surv_nowcast_lineage(), surv_adjusted_prevalence(),
    surv_detection_probability(), surv_required_sequences().
  - Three prevalence estimators: Horvitz-Thompson, Hajek,
    post-stratified.
  - Three allocation objectives: min_mse, max_detection, min_imbalance.
  - Reporting delay estimation with right-truncation correction.
  - Diagnostic tools: surv_compare_estimates(), surv_design_effect().
  - Example dataset: sarscov2_surveillance.
