CRAN release 5.8.2

Package state of CRAN release 5.8.2 (2026-06-05), plus the bundled reproducibility
scripts and results for the SoftwareX paper (inst/examples/ai_assisted/, added
shortly after the CRAN upload).

Changes in 5.8.2 (from NEWS):

• AI_applyAnonymization() gains early stopping of the refinement loop via the new
  tol and patience arguments: refinement terminates once the combined utility
  score U stops improving by more than tol for patience consecutive iterations,
  instead of always running all max_iter rounds.
• query_llm() now omits the temperature parameter for OpenAI GPT-5.x and o-series
  reasoning models (which do not accept a custom temperature), enabling use of e.g. gpt-5.5.
• Bugfix: ldiversity() now computes the distinct l-diversity measure correctly in
  case of NAs in key variables; improved/simplified underlying C++ code; added unit tests.
• Fixed some header definitions for CRAN compliance.
• Updated unit tests for pram().
